I HAVE REFERRED to various union make-work and featherbed practices. These practices, and the public toleration of them, spring from the same fundamental fallacy as the fear of machines. This is the belief that a more efficient way of doing a thing destroys jobs, and its necessary corollary that a less efficient way of doing it creates them.
Allied to this fallacy is the belief that there is just a fixed amount of work to be done in the world, and that, if we cannot add to this work by thinking up more cumbersome ways of doing it, at least we can think of devices for spreading it around among as large a number of people as possible.
This error lies behind the minute subdivision of labor upon which unions insist. In the building trades in large cities the subdivision is notorious. Bricklayers are not allowed to use stones for a chimney: that is the special work of stonemasons. An electrician cannot rip out a board to fix a connection and put it back again: that is the special job, no matter how simple it may be, of the carpenters. A plumber will not remove or put back a tile incident to fixing a leak in the shower: that is the job of a tile-setter.
Furious “jurisdictional” strikes are fought among unions for the exclusive right to do certain types of borderline jobs. In a statement prepared by the American railroads for the Attorney-General’s Committee on Administrative Procedure, the roads gave innumerable examples in which the National Railroad Adjustment Board had decided that
each separate operation on the railroad, no matter how minute, such as talking over a telephone or spiking or unspiking a switch, is so far an exclusive property of a particular class of employee that if an employee of another class, in the course of his regular duties, performs such operations he must not only be paid an extra day’s wages for doing so, but at the same time the furloughed or unemployed members of the class held to be entitled to perform the operation must be paid a day’s wages for not having been called upon to perform it.
It is true that a few persons can profit at the expense of the rest of us from this minute arbitrary subdivision of labor— provided it happens in their case alone. But those who support it as a general practice fail to see that it always raises production costs; that it results on net balance in less work done and in fewer goods produced. The householder who is forced to employ two men to do the work of one has, it is true, given employment to one extra man. But he has just that much less money left over to spend on something that would employ somebody else. Because his bathroom leak has been repaired at double what it should have cost, he decides not to buy the new sweater he wanted. “Labor” is no better off, because a day’s employment of an unneeded tile-setter has meant a day’s disemployment of a sweater knitter or machine handler. The householder, however, is worse off. Instead of having a repaired shower and a sweater, he has the shower and no sweater. And if we count the sweater as part of the national wealth, the country is short one sweater. This symbolizes the net result of the effort to make extra work by arbitrary subdivision of labor.
But there are other schemes for “spreading the work,” often put forward by union spokesmen and legislators. The most frequent of these is the proposal to shorten the working week, usually by law. The belief that it would “spread the work” and “give more jobs” was one of the main reasons behind the inclusion of the penaltyovertime provision in the existing Federal Wage-Hour Law. The previous legislation in the states, forbidding the employment of women or minors for more, say, than forty-eight hours a week, was based on the conviction that longer hours were injurious to health and morale. Some of it was based on the belief that longer hours were harmful to efficiency. But the provision in the federal law, that an employer must pay a worker a 50 percent premium above his regular hourly rate of wages for all hours worked in any week above forty, was not based primarily on the belief that forty-five hours a week, say, was injurious either to health or efficiency. It was inserted partly in the hope of boosting the worker’s weekly income, and partly in the hope that, by discouraging the employer from taking on anyone regularly for more than forty hours a week, it would force him to employ additional workers instead. At the time of writing this, there are many schemes for “averting unemployment” by enacting a thirty-hour week or a four-day week.
What is the actual effect of such plans, whether enforced by individual unions or by legislation? It will clarify the problem if we consider two cases. The first is a reduction in the standard working week from forty hours to thirty without any change in the hourly rate of pay. The second is a reduction in the working week from forty hours to thirty, but with a sufficient increase in hourly wage rates to maintain the same weekly pay for the individual workers already employed.
Let us take the first case. We assume that the working week is cut from forty hours to thirty, with no change in hourly pay. If there is substantial unemployment when this plan is put into effect, the plan will no doubt provide additional jobs. We cannot assume that it will provide sufficient additional jobs, however, to maintain the same payrolls and the same number of man-hours as before, unless we make the unlikely assumptions that in each industry there has been exactly the same percentage of unemployment and that the new men and women employed are no less efficient at their special tasks on the average than those who had already been employed. But suppose we do make these assumptions. Suppose we do assume that the right number of additional workers of each skill is available, and that the new workers do not raise production costs. What will be the result of reducing the working week from forty hours to thirty (without any increase in hourly pay)?
Though more workers will be employed, each will be working fewer hours, and there will, therefore, be no net increase in man-hours. It is unlikely that there will be any significant increase in production. Total payrolls and “purchasing power” will be no larger. All that will have happened, even under the most favorable assumptions (which would seldom be realized) is that the workers previously employed will subsidize, in effect, the workers previously unemployed. For in order that the new workers will individually receive three-fourths as many dollars a week as the old workers used to receive, the old workers will themselves now individually receive only three-fourths as many dollars a week as previously. It is true that the old workers will now work fewer hours; but this purchase of more leisure at a high price is presumably not a decision they have made for its own sake: it is a sacrifice made to provide others with jobs.
The labor union leaders who demand shorter weeks to “spread the work” usually recognize this, and therefore they put the proposal forward in a form in which everyone is supposed to eat his cake and have it too. Reduce the working week from forty hours to thirty, they tell us, to provide more jobs; but compensate for the shorter week by increasing the hourly rate of pay by 33.33 percent. The workers employed, say, were previously getting an average of $226 a week for forty hours work; in order that they may still get $226 for only thirty hours work, the hourly rate of pay must be advanced to an average of more than $7.53.
What would be the consequences of such a plan? The first and most obvious consequence would be to raise costs of production. If we assume that the workers, when previously employed for forty hours, were getting less than the level of production costs, prices and profits made possible, then they could have got the hourly increase without reducing the length of the working week. They could, in other words, have worked the same number of hours and got their total weekly incomes increased by one-third, instead of merely getting, as they are under the new thirty-hour week, the same weekly income as before. But if under the forty-hour week, the workers were already getting as high a wage as the level of production costs and prices made possible (and the very unemployment they are trying to cure may be a sign that they were already getting even more than this), then the increase in production costs as a result of the 33.33 percent increase in hourly wage rates will be much greater than the existing state of prices, production and costs can stand.
The result of the higher wage rate, therefore, will be a much greater unemployment than before. The least efficient firms will be thrown out of business, and the least efficient workers will be thrown out of jobs. Production will be reduced all around the circle. Higher production costs and scarcer supplies will tend to raise prices, so that workers can buy less with the same dollar wages; on the other hand, the increased unemployment will shrink demand and hence tend to lower prices. What ultimately happens to the prices of goods will depend upon what monetary policies are then allowed. But if a policy of monetary inflation is pursued, to enable prices to rise so that the increased hourly wages can be paid, this will merely be a disguised way of reducing real wage rates, so that these will return, in terms of the amount of goods they can purchase, to the same real rate as before. The result would then be the same as if the working week had been reduced without an increase in hourly wage rates. And the results of that have already been discussed.
The spread-the-work schemes, in brief, rest on the same sort of illusion that we have been considering. The people who support such schemes think only of the employment they might provide for particular persons or groups; they do not stop to consider what their whole effect would be on everybody.
The spread-the-work schemes rest also, as we began by pointing out, on the false assumption that there is just a fixed amount of work to be done. There could be no greater fallacy. There is no limit to the amount of work to be done as long as any human need or wish that work could fill remains unsatisfied. In a modern exchange economy, the most work will be done when prices, costs and wages are in the best relations with each other. What these relations are we shall later consider.
Did Robinson Crusoe have money?
How did money begin? Can you eat gold coins?
Crusoe and Friday could just TRADE with each other for the things that they wanted or needed.
To “trade” is to swap, exchange, and barter.
When Crusoe, say, exchanges some fish for lumber, he values the lumber he "buys" more than the fish he "sells," while Friday, on the contrary, values the fish more than the lumber.
The fish may be more valuable than the lumber. The exchange does not have to be equal.
When more and more people come together and more families want to exchange with one another “markets” and “money” start to show up.
Men exchange because they need or want goods, services, or both.
Different people in different places provide different goods and services to exchange.
Exchange is also called commerce.
A system that allows trade is called a market.
The original form of trade is barter, the direct buying and selling of goods and services.
Most of the time modern traders “exchange”, buy and sell, with money.
As a result, buying can be separated from selling, or earning.
Exchange is the lifeblood,
not only of our economy, but of civilization itself.

AMONG THE MOST viable of all economic delusions is the belief that machines on net balance create unemployment. Destroyed a thousand times, it has risen a thousand times out of its own ashes as hardy and vigorous as ever. Whenever there is long-continued mass unemployment, machines get the blame anew. This fallacy is still the basis of many labor union practices. The public tolerates these practices because it either believes at bottom that the unions are right, or is too confused to see just why they are wrong.
The belief that machines cause unemployment, when held with any logical consistency, leads to preposterous conclusions. Not only must we be causing unemployment with every technological improvement we make today, but primitive man must have started causing it with the first efforts he made to save himself from needless toil and sweat.
To go no further back, let us turn to Adam Smith’s Wealth of Nations, published in 1776. The first chapter of this remarkable book is called “Of the Division of Labor,” and on the second page of this first chapter the author tells us that a workman unacquainted with the use of machinery employed in pin-making “could scarce make one pin a day, and certainly could not make twenty,” but with the use of this machinery he can make 4,800 pins a day. So already, alas, in Adam Smith’s time, machinery had thrown from 240 to 4,800 pin-makers out of work for every one it kept. In the pin-making industry there was already, if machines merely throw men out of jobs, 99.98 percent unemployment. Could things be blacker?
Things could be blacker, for the Industrial Revolution was just in its infancy. Let us look at some of the incidents and aspects of that revolution. Let us see, for example, what happened in the stocking industry. New stocking frames as they were introduced were destroyed by the handicraft workmen (over 1000 in a single riot), houses were burned, the inventors were threatened and obliged to flee for their lives, and order was not finally restored until the military had been called out and the leading rioters had been either transported or hanged.
Now it is important to bear in mind that insofar as the rioters were thinking of their own immediate or even longer futures their opposition to the machine was rational. For William Felkin, in his History of the Machine-Wrought Hosiery Manufactures (1867), tells us (though the statement seems implausible) that the larger part of the 50,000 English stocking knitters and their families did not fully emerge from the hunger and misery entailed by the introduction of the machine for the next forty years. But insofar as the rioters believed, as most of them undoubtedly did, that the machine was permanently displacing men, they were mistaken, for before the end of the nineteenth century the stocking industry was employing at least a hundred men for every man it employed at the beginning of the century.
Arkwright invented his cotton-spinning machinery in 1760. At that time it was estimated that there were in England 5,200 spinners using spinning wheels, and 2,700 weavers—in all, 7,900 persons engaged in the production of cotton textiles. The introduction of Arkwright’s invention was opposed on the ground that it threatened the livelihood of the workers, and the opposition had to be put down by force. Yet in 1787—twenty-seven years after the invention appeared—a parliamentary inquiry showed that the number of persons actually engaged in the spinning and weaving of cotton had risen from 7,900 to 320,000, an increase of 4,400 percent.
If the reader will consult such a book as Recent Economic Changes, by David A. Wells, published in 1889, he will find passages that, except for the dates and absolute amounts involved, might have been written by our technophobes of today. Let me quote a few:
During the ten years from 1870 to 1880, inclusive, the British mercantile marine increased its movement, in the matter of foreign entries and clearances alone, to the extent of 22,000,000 tons... yet the number of men who were employed in effecting this great movement had decreased in 1880, as compared with 1870, to the extent of about three thousand (2,990 exactly). What did it? The introduction of steam-hoisting machines and grain elevators upon the wharves and docks, the employment of steam power, etc....
In 1873 Bessemer steel in England, where its price had not been enhanced by protective duties, commanded $80 per ton; in 1886 it was profitably manufactured and sold in the same country for less than $20 per ton. Within the same time the annual production capacity of a Bessemer converter has been increased fourfold, with no increase but rather a diminution of the involved labor.
The power capacity already being exerted by the steam engines of the world in existence and working in the year 1887 has been estimated by the Bureau of Statistics at Berlin as equivalent to that of 200,000,000 horses, representing approximately 1,000,000,000 men; or at least three times the working population of the earth....
One would think that this last figure would have caused Mr. Wells to pause, and wonder why there was any employment left in the world of 1889 at all; but he merely concluded, with restrained pessimism, that “under such circumstances industrial overproduction . . . may become chronic.”
In the depression of 1932, the game of blaming unemployment on the machines started all over again. Within a few months the doctrines of a group calling themselves the Technocrats had spread through the country like a forest fire. I shall not weary the reader with a recital of the fantastic figures put forward by this group or with corrections to show what the real facts were. It is enough to say that the Technocrats returned to the error in all its native purity that machines permanently displace men—except that, in their ignorance, they presented this error as a new and revolutionary discovery of their own. It was simply one more illustration of Santayana’s aphorism that those who cannot remember the past are condemned to repeat it.
The Technocrats were finally laughed out of existence; but their doctrine, which preceded them, lingers on. It is reflected in hundreds of make-work rules and featherbed practices by labor unions; and these rules and practices are tolerated and even approved because of the confusion on this point in the public mind.
Testifying on behalf of the United States Department of Justice before the Temporary National Economic Committee (better known as the TNEC) in March 1941, Corwin Edwards cited innumerable examples of such practices. The electrical union in New York City was charged with refusal to install electrical equipment made outside of New York State unless the equipment was disassembled and reassembled at the job site. In Houston, Texas, master plumbers and the plumbing union agreed that piping prefabricated for installation would be installed by the union only if the thread were cut off one end of the pipe and new thread were cut at the job site. Various locals of the painters’ union imposed restrictions on the use of sprayguns, restrictions in many cases designed merely to make work by requiring the slower process of applying paint with a brush. A local of the teamsters’ union required that every truck entering the New York metropolitan area have a local driver in addition to the driver already employed. In various cities the electrical union required that if any temporary light or power was to be used on a construction job there must be a full-time maintenance electrician, who should not be permitted to do any electrical construction work. This rule, according to Mr. Edwards, “often involves the hiring of a man who spends his day reading or playing solitaire and does nothing except throw a switch at the beginning and end of the day.”
One could go on to cite such make-work practices in many other fields. In the railroad industry, the unions insist that firemen be employed on types of locomotives that do not need them. In the theaters unions insist on the use of scene shifters even in plays in which no scenery is used. The musicians’ union required so-called stand-in musicians or even whole orchestras to be employed in many cases where only phonograph records were needed.
By 1961 there was no sign that the fallacy had died. Not only union leaders but government officials talked solemnly of “automation” as a major cause of unemployment. Automation was discussed as if it were something entirely new in the world. It was in fact merely a new name for continued technological advance and further progress in labor-saving equipment.
But the opposition to labor-saving machinery, even today, is not confined to economic illiterates. As late as 1970, a book appeared by a writer so highly regarded that he has since received the Nobel Prize in economics. His book opposed the introduction of laborsaving machines in the underdeveloped countries on the ground that they “decrease the demand for labor”!* The logical conclusion from this would be that the way to maximize jobs is to make all labor as inefficient and unproductive as possible. It implies that the English Luddite rioters, who in the early nineteenth century destroyed stocking frames, steam-power looms, and shearing machines, were after all doing the right thing.
One might pile up mountains of figures to show how wrong were the technophobes of the past. But it would do no good unless we understood clearly why they were wrong. For statistics and history are useless in economics unless accompanied by a basic deductive understanding of the facts—which means in this case an understanding of why the past consequences of the introduction of machinery and other labor-saving devices had to occur. Otherwise the technophobes will assert (as they do in fact assert when you point out to them that the prophecies of their predecessorsturned out to be absurd): “That may have been all very well in the past but today conditions are fundamentally different; and now we simply cannot afford to develop any more labor-saving machines.” Mrs. Eleanor Roosevelt, indeed, in a syndicated newspaper column of September19, 1945, wrote: “We have reached a point today where labor-saving devices are good only when they do not throw the worker out of his job.”
If it were indeed true that the introduction of labor-saving machinery is a cause of constantly mounting unemployment and misery, the logical conclusions to be drawn would be revolutionary, not only in the technical field but for our whole concept of civilization. Not only should we have to regard all further technical progress as a calamity; we should have to regard all past technical progress with equal horror. Every day each of us in his own activity is engaged in trying to reduce the effort it requires to accomplish a given result. Each of us is trying to save his own labor, to economize the means required to achieve his ends. Every employer, small as well as large, seeks constantly to gain his results more economically and efficiently— that is, by saving labor. Every intelligent workman tries to cut down the effort necessary to accomplish his assigned job. The most ambitious of us try tirelessly to increase the results we can achieve in a given number of hours. The technophobes, if they were logical and consistent, would have to dismiss all this progress and ingenuity as not only useless but vicious. Why should freight be carried from Chicago to New York by railroad when we could employ enormously more men, for example, to carry it all on their backs?
Theories as false as this are never held with logical consistency, but they do great harm because they are held at all. Let us, therefore, try to see exactly what happens when technical improvements and labor-saving machinery are introduced. The details will vary in each instance, depending upon the particular conditions that prevail in a given industry or period. But we shall assume an example that involves the main possibilities.
Suppose a clothing manufacturer learns of a machine that will make men’s and women s overcoats for half as much labor as previously. He installs the machines and drops half his labor force.
This looks at first glance like a clear loss of employment. But the machine itself required labor to make it; so here, as one offset, are jobs that would not otherwise have existed. The manufacturer, however, would have adopted the machine only if it had either made better suits for half as much labor, or had made the same kind of suits at a smaller cost. If we assume the latter, we cannot assume that the amount of labor to make the machines was as great in terms of payrolls as the amount of labor that the clothing manufacturer hopes to save in the long run by adopting the machine; otherwise there would have been no economy, and he would not have adopted it.
So there is still a net loss of employment to be accounted for. But we should at least keep in mind the real possibility that even the first effect of the introduction of labor-saving machinery may be to increase employment on net balance; because it is usually only in the long run that the clothing manufacturer expects to save money by adopting the machine: it may take several years for the machine to “pay for itself.”
After the machine has produced economies sufficient to offset its cost, the clothing manufacturer has more profits than before. (We shall assume that he merely sells his coats for the same price as his competitors and makes no effort to undersell them.) At this point, it may seem, labor has suffered a net loss of employment, while it is only the manufacturer, the capitalist, who has gained. But it is precisely out of these extra profits that the subsequent social gains must come. The manufacturer must use these extra profits in at least one of three ways, and possibly he will use part of them in all three: (1) he will use the extra profits to expand his operations by buying more machines to make more coats; or (2) he will invest the extra profits in some other industry; or (3) he will spend the extra profits on increasing his own consumption. Whichever of these three courses he takes, he will increase employment.
In other words, the manufacturer, as a result of his economies, has profits that he did not have before. Every dollar of the amount he has saved in direct wages to former coat makers, he now has to pay out in indirect wages to the makers of the new machine, or to the workers in another capital-using industry, or to the makers of a new house or car for himself or for jewelry and furs for his wife. In any case (unless he is a pointless hoarder) he gives indirectly as many jobs as he ceased to give directly.
But the matter does not and cannot rest at this stage. If this enterprising manufacturer effects great economies as compared with his competitors, either he will begin to expand his operations at their expense, or they will start buying the machines too. Again more work will be given to the makers of the machines. But competition and production will then also begin to force down the price of overcoats. There will no longer be as great profits for those who adopt the new machines. The rate of profit of the manufacturers using the new machine will begin to drop, while the manufacturers who have still not adopted the machine may now make no profit at all. The savings, in other words, will begin to be passed along to the buyers of overcoats—to the consumers.
But as overcoats are now cheaper, more people will buy them. This means that, though it takes fewer people to make the same number of overcoats as before, more overcoats are now being made than before. If the demand for overcoats is what economists call “elastic”—that is, if a fall in the price of overcoats causes a larger total amount of money to be spent on overcoats than previously— then more people may be employed even in making overcoats than before the new labor-saving machine was introduced. We have already seen how this actually happened historically with stockings and other textiles.
But the new employment does not depend on the elasticity of demand for the particular product involved. Suppose that, though the price of overcoats was almost cut in half—from a former price, say, of $150 to a new price of $100—not a single additional coat was sold. The result would be that while consumers were as well provided with new overcoats as before, each buyer would now have $50 left over that he would not have had left over before. He will therefore spend this $50 for something else, and so provide increased employment in other lines.
In brief, on net balance machines, technological improvements, automation, economies and efficiency do not throw men out of work.
Not all inventions and discoveries, of course, are “labor-saving” machines. Some of them, like precision instruments, like nylon, lucite, plywood and plastics of all kinds, simply improve the quality of products. Others, like the telephone or the airplane, perform operations that direct human labor could not perform at all. Still others bring into existence objects and services, such as X-ray machines, radios, TV sets, air-conditioners and computers, that would otherwise not even exist. But in the foregoing illustration we have taken precisely the kind of machine that has been the special object of modern technophobia.
It is possible, of course, to push too far the argument that machines do not on net balance throw men out of work. It is sometimes argued, for example, that machines create more jobs than would otherwise have existed. Under certain conditions this may be true. They can certainly create enormously more jobs in particular trades. The eighteenth century figures for the textile industries are a case in point. Their modern counterparts are certainly no less striking. In 1910, 140,000 persons were employed in the United States in the newly created automobile industry. In 1920, as the product was improved and its cost reduced, the industry employed 250,000 In 1930, as this product improvement and cost reduction continued, employment in the industry was 380,000. In 1973 it had risen to 941,000. By 1973, 514,000 people were employed in making aircraft and aircraft parts, and 393,000 were engaged in making electronic components. So it has been in one newly created trade after another, as the invention was improved and the cost reduced.2
There is also an absolute sense in which machines may be said to have enormously increased the number of jobs. The population of the world today is four times as great as in the middle of the eighteenth century, before the Industrial Revolution had got well under way. Machines may be said to have given birth to this increased population; for without the machines, the world would not have been able to support it. Three out of every four of us, therefore, may be said to owe not only our jobs but our very lives to machines.
Yet it is a misconception to think of the function or result of machines as primarily one of creating jobs. The real result of the machine is to increase production, to raise the standard of living, to increase economic welfare. It is no trick to employ everybody, even (or especially) in the most primitive economy. Full employment—very full employment; long, weary, backbreaking employment—is characteristic of precisely the nations that are most retarded industrially. Where full employment already exists, new machines, inventions and discoveries cannot—until there has been time for an increase in population — bring more employment. They are likely to bring more unemployment (but this time I am speaking of voluntaiy and not involuntary unemployment) because people can now afford to work fewer hours, while children and the overaged no longer need to work.
What machines do, to repeat, is to bring an increase in production and an increase in the standard of living. They may do this in either of two ways. They do it by making goods cheaper for consumers (as in our illustration of the overcoats), or they do it by increasing wages because they increase the productivity of the workers. In other words, they either increase money wages or, by reducing prices, they increase the goods and services that the same money wages will buy. Sometimes they do both. What actually happens will depend in large part upon the monetary policy pursued in a country. But in any case, machines, inventions and discoveries increase real wages.
A warning is necessary before we leave this subject. It was precisely the great merit of the classical economists that they looked for secondary consequences, that they were concerned with the effects of a given economic policy or development in the long run and on the whole community. But it was also their defect that, in taking the long view and the broad view, they sometimes neglected to take also the short view and the narrow view. They were too often inclined to minimize or to forget altogether the immediate effects of developments on special groups. We have seen, for example, that many of the English stocking knitters suffered real tragedies as a result of the introduction of the new stocking frames, one of the earliest inventions of the Industrial Revolution.
But such facts and their modern counterparts have led some writers to the opposite extreme of looking only at the immediate effects on certain groups. Joe Smith is thrown out of a job by the introduction of some new machine. “Keep your eye on Joe Smith,” these writers insist. “Never lose track of Joe Smith.” But what they then proceed to do is to keep their eyes only on Joe Smith, and to forget Tom Jones, who has just got a new job in making the new machine, and Ted Brown, who has just got a job operating one, and Daisy Miller, who can now buy a coat for half what it used to cost her. And because they think only of Joe Smith, they end by advocating reactionary and nonsensical policies.
Yes, we should keep at least one eye on Joe Smith. He has been thrown out of a job by the new machine. Perhaps he can soon get another job, even a better one. But perhaps, also, he has devoted many years of his life to acquiring and improving a special skill for which the market no longer has any use. He has lost this investment in himself, in his old skill, just as his former employer, perhaps, has lost his investment in old machines or processes suddenly rendered obsolete. He was a skilled workman, and paid as a skilled workman. Now he has become overnight an unskilled workman again, and can hope, for the present, only for the wages of an unskilled workman, because the one skill he had is no longer needed. We cannot and must not forget Joe Smith. His is one of the personal tragedies that, as we shall see, are incident to nearly all industrial and economic progress.
To ask precisely what course we should follow with Joe Smith —whether we should let him make his own adjustment, give him separation pay or unemployment compensation, put him on relief, or train him at government expense for a new job—would carry us beyond the point that we are here trying to illustrate. The central lesson is that we should try to see all the main consequences of any economic policy or development—the immediate effects on special groups, and the long-run effects on all groups.
If we have devoted considerable space to this issue, it is because our conclusions regarding the effects of new machinery, inventions and discoveries on employment, production and welfare are crucial. If we are wrong about these, there are few things in economics about which we are likely to be right.
