There are two types of ethical criticisms that can be made of the free-market system. One type is purely existential; that is, it rests on existential premises only. The other type advances conflicting ethical goals and protests that the free market does not attain these goals...

Number 1: Knowledge of Self-Interest: An Alleged Critical Assumption

This criticism of the market is more existential than ethical. It is the popular argument that laissez faire, or the free-market economy, rests its case on the crucial assumption that every individual knows his own self-interest best. Yet, it is charged, this is not true of many individuals. Therefore, the State must intervene, and the case for the free market is vitiated.

The free-market doctrine, however, does not rest on any such assumption. Like the mythical "economic man," the Perfectly Wise Individual is a straw man created by the critics of the theory, not implied by it.

First, it should be evident from our analysis of the free market and government intervention throughout this work that any argument for the free market rests on a far deeper and more complex doctrine. We cannot enter here into the many ethical and philosophical arguments for freedom. Secondly, the laissez-faire or free-market doctrine does not assume that everyone always knows his own interest best; it asserts rather that everyone should have the right to be free to pursue his own interest as he deems best.

Critics may argue that the government should force men to lose some ex ante or present utility in order to gain ex post utility later, by being compelled to pursue their own best interests.

But libertarians may well reply in rebuttal: (1) that a person's resentment at coercive interference will lower his ex post utility in any event; and (2) that the condition of freedom is a vital, necessary prerequisite for a person's "best interests" to be attained. Indeed, the only lasting way to correct a person's errors is by persuasive reasoning; force cannot do the job. As soon as the individual can evade this force, he will return to his own preferred ways.

No one, certainly, has perfect foresight into the uncertain future. But free entrepreneurs on the market are better equipped than anyone else, by incentive and by economic calculation, to foresee and satisfy the needs of the consumers.

But what if the consumers are mistaken with regard to their own interests? Obviously, they sometimes are. But several more points must be made. In the first place, every individual knows the data of his own inner self best—by the very fact that each has a separate mind and ego. Secondly, the individual, if in doubt about what his own true interests are, is free to hire and consult experts to give him advice based on their superior knowledge. The individual hires these experts and, on the market, can continuously test their helpfulness. Individuals on the market, in short, tend to patronize those experts whose advice proves most successful. Good doctors or lawyers reap rewards on the free market, while poor ones fail. But when government intervenes, the government expert acquires his revenue by compulsory levy. There is no market test of his success in teaching people their true interests. The only test is his success in acquiring the political support of the State's machinery of coercion.

Thus, the privately hired expert flourishes in proportion to his ability, whereas the government expert flourishes in proportion to his success in currying political favor. Moreover, what incentive does the government expert have to care about the interests of his subjects? Surely he is not especially endowed with superior qualities by virtue of his government post. He is no more virtuous than the private expert; indeed, he is inherently less capable and is more inclined to wield coercive force. But while the private expert has every pecuniary incentive to care about his clients or patients, the government expert has no incentive whatever. He obtains his revenue in any event. He is devoid of any incentive to worry about his subject's true interests.

It is curious that people tend to regard government as a quasi-divine, selfless, Santa Claus organization. Government was constructed neither for ability nor for the exercise of loving care; government was built for the use of force and for necessarily demagogic appeals for votes. If individuals do not know their own interests in many cases, they are free to turn to private experts for guidance. It is absurd to say that they will be served better by a coercive, demagogic apparatus.

Finally, the proponents of government intervention are trapped in a fatal contradiction: they assume that individuals are not competent to run their own affairs or to hire experts to advise them. And yet they also assume that these same individuals are equipped to vote for these same experts at the ballot box. We have seen that, on the contrary, while most people have a direct idea and a direct test of their own personal interests on the market, they cannot understand the complex chains of praxeological and philosophical reasoning necessary for a choice of rulers or political policies. Yet this political sphere of open demagogy is precisely the only one where the mass of individuals are deemed to be competent!

Number 2: The Problem of Immoral Choices

Some writers are astute enough to realize that the market economy is simply a resultant of individual valuations, and thus they see that, if they do not like the results, the fault lies with the valuations, not the economic system. Yet they proceed to advocate government intervention to correct the immorality of individual choices. If people are immoral enough to choose whiskey rather than milk, cosmetics rather than educational matter, then the State, they say, should step in and correct these choices. Much of the rebuttal parallels the refutation of the knowledge-of-interests argument; i.e., it is self-contradictory to contend that people cannot be trusted to make moral decisions in their daily lives but can be trusted to vote for or accept leaders who are morally wiser than they.

Mises states, quite rightly, that anyone who advocates governmental dictation over one area of individual consumption must logically come to advocate complete totalitarian dictation over all choices. This follows if the dictators have any set of valuational principles whatever. Thus, if the members of the ruling group like Bach and hate Mozart, and they believe strongly that Mozartian music is immoral, they are just as right in prohibiting the playing of Mozart as they are in prohibiting drug use or liquor consumption. Many statists, however, would not balk at this conclusion and would be willing to take over this congenial task.

The utilitarian position—that government dictation is bad because no rational ethics exists, and therefore no person has a right to impose his arbitrary values on someone else—is, we believe, an inadequate one. In the first place, it will not convince those who believe in a rational ethics, who believe that there is a scientific basis for moral judgments and that they are not pure whim. And furthermore, the position involves a hidden moral assumption of its own—that A has no right to impose any arbitrary values on B. But if ends are arbitrary, is not the end "that arbitrary whims not be imposed by coercion" just as arbitrary? And suppose, further, that ranking high on A's value scale is the arbitrary whim of imposing his other values on B. Then the utilitarians cannot object and must abandon their attempt to defend individual liberty in a value-free manner. In fact, the utilitarians are helpless against the man who wants to impose his values by coercion and who persists in doing so even after the various economic consequences are pointed out to him.

The would-be dictator can be logically refuted in a completely different way, even while remaining within Wertfrei praxeological bounds. For what is the complaint of the would-be dictator against free individuals? That they act immorally in various ways. The dictator's aim, therefore, is to advance morality and combat immorality. Let us grant, for the sake of argument, that an objective morality can be arrived at. The question that must be faced, then, is: Can force advance morality? Suppose we arrive at the demonstrable conclusion that actions A, B, and C are immoral, and actions X, Y, and Z are moral. And suppose we find that Mr. Jones shows a distressing propensity to value A, B, and C highly and adopts these courses of action time and again. We are interested in transforming Mr. Jones from being an immoral person to being a moral person. How can we go about it? The statists answer: by force. We must prohibit at gunpoint Mr. Jones from doing A, B, and C. Then, at last, he will be moral. But will he? Is Jones moral because he chooses X when he is forcibly deprived of the opportunity to choose A? When Smith is confined to a prison, is he being moral because he doesn't spend his time in saloons getting drunk?

There is no sense to any concept of morality, regardless of the particular moral action one favors, if a man is not free to do the immoral as well as the moral thing. If a man is not free to choose, if he is compelled by force to do the moral thing, then, on the contrary, he is being deprived of the opportunity of being moral. He has not been permitted to weigh the alternatives, to arrive at his own conclusions, and to take his stand. If he is deprived of free choice, he is acting under the dictator's will rather than his own. (Of course, he could choose to be shot, but this is hardly an intelligible conception of free choice of alternatives. In fact, he then has only one free choice: the hegemonic one—to be shot or to obey the dictator in all things.)

Dictatorship over consumers' choices, then, can only atrophy morality rather than promote it. There is but one way that morality can spread from the enlightened to the unenlightened—and that is by rational persuasion. If A convinces B through the use of reason that his moral values are correct and B's are wrong, then B will change and adopt the moral course of his own free will. To say that this method is a slower procedure is beside the point. The point is that morality can spread only through peaceful persuasion and that the use of force can only erode and impair morality.

We have not even mentioned other facts that strengthen our argument, such as the great difficulty in enforcing dictatorial rules against people whose values clash with them. The man who prefers the immoral course and is prevented by the bayonet from acting on his preference will do his best to find ways to circumvent the prohibition—perhaps by bribing the bayoneteer. And, because this is not a treatise on ethics, we have not mentioned the libertarian ethical theory which holds that the use of coercion is itself the highest form of immorality.

Thus, we have shown that would-be dictators must necessarily fail to achieve their professed goal of advancing morality because the consequences will be precisely the opposite. It is possible, of course, that the dictators are not really sincere in stating their goal; perhaps their true purpose is to wield power over others and to prevent others from being happy. In that case, of course, praxeology can say no more about the matter, although ethics may find a good deal to say.

Number 3: The Morality of Human Nature

It is very common to assert that the advocates of the purely free market make one fundamental and shaky assumption: that all human beings are angels. In a society of angels, it is commonly agreed, such a program could "work," but not in our fallible world. The chief difficulty with this criticism is that no libertarian—except possibly those under Tolstoyan influence—has ever made such an assumption. The advocates of the free market have not assumed a reformation of human nature, although they would certainly have no objection to such a reformation if it took place. We have seen that libertarians envision defense services against predators as provided by private bodies rather than by the State. But they do not assume that crime would magically disappear in the free society.

Statists concede to libertarians that no State would be required if all men were "good." State control is allegedly required only to the extent that men are "evil." But what if all men were "evil"? As F.A. Harper has pointed out:

Still using the same principle that political rulership should be employed to the extent of the evil in man, we would then have a society in which complete political rulership of all the affairs of everybody would be called for. . . . One man would rule all. But who would serve as the dictator? However he were to be selected and affixed to the political throne, he would surely be a totally evil person, since all men are evil. And this society would then be ruled by a totally evil dictator possessed of total political power. And how, in the name of logic, could anything short of total evil be its consequence? How could it be better than having no political rulership at all in that society?

Is this argument unrealistic because, as everyone agrees, human beings are a compound, capable of both good and evil? But then, at what point in this mixture does State dictation become necessary? In fact, the libertarian would reason that the fact that human nature is a mixture of both good and evil provides its own particular argument in his favor. For if man is such a mixture, then the best societal framework is surely one in which evil is discouraged and the good encouraged. The libertarian maintains that the existence of the State apparatus provides a ready, swift channel for the exercise of evil, since the rulers of the State are thereby legitimated and can wield compulsion in ways that no one else is permitted to do. What is considered "crime" socially, is called "exercise of democratic power" when performed by an individual as a State official. The purely free market, on the other hand, eliminates all legitimated channels for the exercise of power over man.

Number 4: The Alleged Need for Equality

Probably the most common ethical criticism of the market economy is that it fails to achieve the goal of equality. Equality has been championed on various "economic" grounds, such as minimum social sacrifice or the diminishing marginal utility of money (see the chapter on taxation above). But in recent years economists have recognized that they cannot justify egalitarianism by economics, that they ultimately need an ethical basis for equality.

Economics or praxeology cannot establish the validity of ethical ideals, but even ethical goals must be framed meaningfully. They must therefore pass muster before praxeology as being internally consistent and conceptually possible. The credentials of "equality" have so far not been adequately tested.

It is true that many objections have been raised that give egalitarians pause. Sometimes realization of the necessary consequences of their policies causes an abandonment, though more often a slowing down, of the egalitarian program. Thus: compulsory equality will demonstrably stifle incentive, eliminate the adjustment processes of the market economy, destroy all efficiency in satisfying consumer wants, greatly lower capital formation, and cause capital consumption—all effects signifying a drastic fall in general standards of living. Furthermore, only a free society is casteless, and therefore only freedom will permit mobility of income according to productivity. Statism, on the other hand, is likely to freeze the economy into a mold of (nonproductive) inequality.

Yet these arguments, though powerful, are by no means conclusive. Some people will pursue equality anyway; many will take these considerations into account by settling for some cuts in living standards in order to gain more equality.

In all discussions of equality, it is considered self-evident that equality is a very worthy goal. But this is by no means self-evident. For the very goal of equality itself is open to serious challenge. The doctrines of praxeology are deduced from three universally acceptable axioms: the major axiom of the existence of purposive human action; and the minor postulates, or axioms, of the diversity of human skills and natural resources, and the disutility of labor. Although it is possible to construct an economic theory of a society without these two minor axioms (but not without the major one), they are included in order to limit our theorizing to laws that can apply directly to reality. Anyone who wants to set forth a theory applicable to interchangeable human beings is welcome to do so.

Thus, the diversity of mankind is a basic postulate of our knowledge of human beings. But if mankind is diverse and individuated, then how can anyone propose equality as an ideal? Every year, scholars hold Conferences on Equality and call for greater equality, and no one challenges the basic tenet. But what justification can equality find in the nature of man? If each individual is unique, how else can he be made "equal" to others than by destroying most of what is human in him and reducing human society to the mindless uniformity of the ant heap? It is the task of the egalitarian, who confidently enters the scene to inform the economist of his ultimate ethical goal, to prove his case. He must show how equality can be compatible with the nature of mankind and must defend the feasibility of a possible egalitarian world.

But the egalitarian is in even direr straits, for it can be shown that equality of income is an impossible goal for mankind. Income can never be equal. Income must be considered, of course, in real and not in money terms; otherwise there would be no true equality. Yet real income can never be equalized. For how can a New Yorker's enjoyment of the Manhattan skyline be equalized with an Indian's? How can the New Yorker swim in the Ganges as well as an Indian? Since every individual is necessarily situated in a different space, every individual's real income must differ from good to good and from person to person. There is no way to combine goods of different types, to measure some income "level," so it is meaningless to try to arrive at some sort of "equal" level. The fact must be faced that equality cannot be achieved because it is a conceptually impossible goal for man, by virtue of his necessary dispersion in location and diversity among individuals. But if equality is an absurd (and therefore irrational) goal, then any effort to approach equality is correspondingly absurd. If a goal is pointless, then any attempt to attain it is similarly pointless.

Many people believe that, though equality of income is an absurd ideal, it can be replaced by the ideal of equality of opportunity. Yet this, too, is as meaningless as the former concept. How can the New Yorker's opportunity and the Indian's opportunity to sail around Manhattan, or to swim in the Ganges, be "equalized"? Man's inevitable diversity of location effectively eliminates any possibility of equalizing "opportunity."…

Human life is not some sort of race or game in which each person should start from an identical mark. It is an attempt by each man to be as happy as possible. And each person could not begin from the same point, for the world has not just come into being; it is diverse and infinitely varied in its parts. The mere fact that one individual is necessarily born in a different place from someone else immediately insures that his inherited opportunity cannot be the same as his neighbor's. The drive for equality of opportunity would also require the abolition of the family since different parents have unequal abilities; it would require the communal rearing of children. The State would have to nationalize all babies and raise them in State nurseries under "equal" conditions. But even here conditions cannot be the same, because different State officials will themselves have different abilities and personalities. And equality can never be achieved because of necessary differences of location.

Thus, the egalitarian must not be permitted any longer to end discussion by simply proclaiming equality as an absolute ethical goal. He must first face all the social and economic consequences of egalitarianism and try to show that it does not clash with the basic nature of man. He must counter the argument that man is not made for a compulsory ant heap existence. And, finally, he must recognize that the goals of equality of income and equality of opportunity are conceptually unrealizable and are therefore absurd. Any drive to achieve them is ipso facto absurd as well.

Egalitarianism is, therefore, a literally senseless social philosophy. Its only meaningful formulation is the goal of "equality of liberty"—formulated by Herbert Spencer in his famous Law of Equal Freedom: "Every man has freedom to do all he wills, provided he infringes not the equal freedom of any other man." This goal does not attempt to make every individual's total condition equal—an absolutely impossible task; instead, it advocates liberty—a condition of absence of coercion over person and property for every man.

Yet even this formulation of equality has many flaws and could profitably be discarded. In the first place, it opens the door for ambiguity and for egalitarianism. In the second place, the term "equality" connotes measurable identity with a fixed, extensive unit. "Equal length" means identity of measurement with an objectively determinable unit. In the study of human action, whether in praxeology or social philosophy, there is no such quantitative unit, and hence there can be no such "equality." Far better to say that "each man should have X" than to say that "all men should be equal in X." If someone wants to urge every man to buy a car, he formulates his goal in that way—"Every man should buy a car"—rather than in such terms as: "All men should have equality in car buying." The use of the term "equality" is awkward as well as misleading.

And finally, as Clara Dixon Davidson pointed out so cogently many years ago, Spencer's Law of Equal Freedom is redundant. For if every man has freedom to do all that he wills, it follows from this very premise that no man's freedom has been infringed or invaded. The whole second clause of the law after "wills" is redundant and unnecessary. Since the formulation of Spencer's Law, opponents of Spencer have used the qualifying clause to drive holes into the libertarian philosophy. Yet all this time they were hitting at an encumbrance, not at the essence of the law. The concept of "equality" has no rightful place in the "Law of Equal Freedom," being replaceable by the logical quantifier "every." The "Law of Equal Freedom" could well be renamed "The Law of Total Freedom."

Number 5: The Problem of Security

One of the most common ethical charges leveled at the free market is that it fails to provide "security." It is said that the blessings of freedom must be weighed against the competing blessings of security—to be provided, of course, by the State.

The first comment to make is that this world is a world of uncertainty. We shall never be able to forecast the future course of the world with precision. Every action, therefore, involves risk. This risk cannot be eliminated. The man who keeps cash balances suffers the risk that its purchasing power may dwindle; the man who invests suffers the risk of loss; and so forth.

Yet the free market finds ways of voluntarily relieving risk as much as can possibly be done. In a free society there are three prime ways that men can alleviate uncertainty about the future:

(1) By savings. These savings, whether invested in production or kept in cash balances, insure money for future needs. Investing in production increases one's future assets; cash balances insure that funds will be immediately available.

(2) By entrepreneurship. The entrepreneurs, i.e., the capitalist-entrepreneurs, assume the bulk of the risks of the market and concomitantly relieve laborers of a great deal of risk. Imagine the universal risk if laborers could not be paid until the final product reached the consumers! The pain of waiting for future income, the risk in attempting to forecast consumer demands in the future, would be almost intolerable, especially for those laborers toiling in the most remote processes of production. It is difficult to see how anyone would embark on longer processes of production if he were forced to wait the entire length of the production period to earn any income. But the capitalist-entrepreneur pays him, instead, immediately and himself adopts the burden of waiting and forecasting future wants. The entrepreneur then risks loss of his capital. Another method of entrepreneurial assumption of risk takes place in futures markets, where hedging allows buyers and sellers of commodities to shift the risk of future price changes onto a body of specialized traders.

(3) By insurance. Insurance is a basic method of pooling and abating risks on the market. While entrepreneurs assume the burdens of uncertainty, insurance takes care of actuarial risks, where stable collective frequencies can be arrived at and premiums can be charged accordingly.

The State cannot provide absolute security. The slaves may have believed that their security was guaranteed by their master. But the master assumed the risk; if his income fell, then he could not provide security for his charges.

A fourth way to provide security in a free society is by voluntary charity. This charity, of necessity, comes out of production. It has been maintained that the State can provide security for the people better than the market because it can guarantee a minimum income for everyone. Yet the government can do no such thing. The State produces nothing; it can only confiscate the production of others. The State, therefore, can guarantee nothing; if the requisite minimum is not produced, the State will have to default on its pledges. Of course, the State can print all the money it wants, but it cannot produce the needed goods. Furthermore, the State cannot, in this way, provide security for every man alike. It can make some secure only at the expense of others. If A can be made more secure only by robbing B, B is made more insecure in the process. Hence, the State, even if production is not drastically reduced, cannot provide security for all, but only for some at the expense of others.

Is there no way, then, that government—organized coercion—can provide security? Yes, but not in the absolute sense. Rather, it can provide a certain aspect of security, and only this aspect can be guaranteed to every man in the society. This is security against aggression. In fact, however, only a voluntary, free-market defense can provide this, since only such a non-Statist type of defense agency does not itself engage in aggression. With each man acquiring security of person and property against attack, productivity and leisure are both immeasurably increased. Any State attempt to provide such security is an anachronism, since the State itself constantly invades individual liberty and security.

That type of security, then, which is open to every man in society, is not only compatible with, but is a corollary to, perfect freedom. Freedom and security against aggression are two sides of the same coin.

It might still be objected that many people, even knowing that slavery or submission to dictation cannot bring absolute security, will still wish to rely on masters. But if they do so voluntarily, the libertarian asks, why must they force others, who do not choose to submit to masters, to join them?

Number 6: Alleged Joys of the Society of Status

One common related criticism of the free market and free society (particularly among intellectuals who are conspicuously not craftsmen or peasants) is that, in contrast to the Happy Craftsmen and Happy Peasants of the Middle Ages, it has "alienated" man from his work and from his fellows and has robbed him of his "sense of belonging." The status society of the Middle Ages is looked back upon as a Golden Age, when everyone was sure of his station in life, when craftsmen made the whole shoe instead of just contributing to part of its production, and when these "whole" laborers were enmeshed in a sense of belonging with the rest of society.

In the first place, the society of the Middle Ages was not a secure one, not a fixed, unchanging hierarchy of status. There was little progress, but there was much change. Dwelling as they did in clusters of local self-sufficiency, marked by a low standard of living, the people were ever threatened by famine. And because of the relative absence of trade, a famine in one area could not be countered by purchasing food from another area. The absence of famine in capitalist society is not a providential coincidence. Secondly, because of the low living standards, very few members of the population were lucky enough to be born into the status of the Happy Craftsman, who could be really happy and secure in his work only if he were a craftsman to the King or the nobility (who, of course, earned their high status by the decidedly "unhappy" practice of permanent violence in domination over the mass of the exploited population). As for the common serf, one wonders whether, in his poverty-stricken, enslaved, and barren existence, he had even sufficient time and leisure to contemplate the supposed joys of his fixed post and his "sense of belonging." And if there were a serf or two who did not wish to "belong" to his lord or master, that "belonging," of course, was enforced by violence.

Aside from these considerations, there is another problem which the society of status cannot surmount, and which indeed contributed a great deal to breaking up the feudal and mercantilist structures of the precapitalistic era. This was population growth. If everyone is assigned his appointed and inherited role in life, how can an increased population be fitted into the scheme? Where are they to be assigned, and who is to do the assigning? And wherever they are allocated, how can these new people be prevented from disrupting the whole assigned network of custom and status?

In short, it is precisely in the fixed, noncapitalistic society of status that the Malthusian problem is ever present, at its ugliest, and where Malthusian "checks" to population must come into play. Sometimes the check is the natural one of famine and plague; in other societies, systematic infanticide is practiced. Perhaps if there were a modern return to the society of status, compulsory birth control would be the rule (a not impossible prognosis for the future). But in precapitalist Europe, the population problem became a problem of an ever increasing number of people with no work to do and no place to go, who therefore had to turn to begging or highway robbery.

The proponents of the theory of modern "alienation" do not offer any reasoning to back up their assertions, which are therefore simply dogmatic myths. Certainly, it is not self-evident that the craftsman, or better still, the primitive man who made everything that he consumed, was in some sense happier or "more whole" as a result of this experience. Although this is not a treatise on psychology, it might be noted that perhaps what gives the worker his sense of importance is his participation in what Isabel Paterson has called the "circuit of production." In free-market capitalism he can, of course, participate in that circuit in many more and varied ways than he could in the more primitive status society.

Furthermore, the status society is a tragic waste of potential skill for the individual worker. There is, after all, no reason why the son of a carpenter should be particularly interested or skilled in carpentry. In the status society he faces only a dreary life of carpentry, regardless of his desires. In the free-market, capitalist society, though he is of course not guaranteed that he will be able to make a livelihood in any line of work that he wants to pursue, his opportunities to do work that he really likes are immeasurably, almost infinitely, expanded.

As the division of labor expands, there are more and more varieties of skilled occupations that he can engage in, instead of having to be content with only the most primitive skills. And in the free society he is free to try these tasks, free to move into whatever area he likes best. He has no freedom and no opportunity in the allegedly joyful society of status. Just as free capitalism enormously expanded the amount and variety of consumers' goods and services available to mankind, so it vastly expanded the number and variety of jobs to be done and the skills that people can develop.

The hullabaloo about "alienation" is, in fact, more than a glorification of the medieval craftsman. He, after all, bought his food from the nearby land. It is actually an attack on the whole concept of the division of labor and an enshrining of primitive self-sufficiency. A return to such conditions could mean only the eradication of the bulk of today's population and complete impoverishment for those remaining. Why "happiness" would nonetheless increase, we leave to the mythologists of status.

But there is one final consideration which indicates that the vast majority of the people do not believe that they need primitive conditions and the slave's sense of belonging to make them happy. For there is nothing, in a free society, to prevent those who wish from going off in separate communities and living primitively and "belongingly." No one is forced to join the specialized division
