"A largely parallel example involving human behavior has been used elsewhere by Savage and me. Consider the problem of predicting the shots made by an expert billiard player. It seems not at all unreasonable that excellent predictions would be yielded by the hypothesis that the billiard player made his shots as if he knew the complicated mathematical formulas that would give the optimum directions of travel, could estimate accurately by eye the angles, etc., describing the location of the balls, could make lightning calculations from the formulas, and could then make the balls travel in the direction indicated by the formulas. Our confidence in this hypothesis is not based on the belief that billiard players, even expert ones, can or do go through the process described; it derives rather from the belief that, unless in some way or other they were capable of reaching essentially the same result, they would not in fact be expert billiard players. It is only a short step from these examples to the economic hypothesis that under a wide range of circumstances individual firms behave as if they were seeking rationally to maximize their expected returns (generally if misleadingly called "profits") and had full knowledge of the data needed to succeed in this attempt; as if, that is, they knew the relevant cost and demand functions, calculated marginal cost and marginal revenue from all actions open to them, and pushed each line of action to the point at which the relevant marginal cost and marginal revenue were equal. Now, of course, businessmen do not actually and literally solve the system of simultaneous equations in terms of which the mathematical economist finds it convenient to express this hypothesis, any more than leaves or billiard players explicitly go through complicated mathematical calculations or falling bodies decide to create a vacuum. The billiard player, if asked how he decides where to hit the ball, may say that he "just figures it out" but then also rubs a rabbit's foot just to make sure; and the businessman may well say that he prices at average cost, with of course some minor deviations when the market makes it necessary. The one statement is about as helpful as the other, and neither is a relevant test of the associated hypothesis."

"Whether it is in the slums of New Delhi or in the affluence of Las Vegas, it simply isn't fair that there should be any losers. Life is unfair — there is nothing fair about one man being born blind and another man being born with sight. There is nothing fair about one man being born of a wealthy parent and one of an impecunious parent. There is nothing fair about Muhammad Ali having been born with a skill that enables him to make millions of dollars one night. There is nothing fair about Marlene Dietrich having great legs that we all want to watch. There is nothing fair about any of that. But on the other hand, don't you think a lot of people who like to look at Marlene Dietrich's legs benefited from nature's unfairness in producing a Marlene Dietrich. What kind of a world would it be if everybody was an absolute identical duplicate of anybody else. You might as well destroy the whole world and just keep one specimen left for a museum. In the same way, it's unfair that Muhammad Ali should be a great fighter and should be able to earn millions. But would it not be even more unfair to the people who like to watch him if you said that in the pursuit of some abstract idea of equality we're not going to let Muhammad Ali get more for one nights fight than the lowest man on the totem pole can get for a days unskilled work on the docks. You can do that but the result of that would be to deny people the opportunity to watch Muhammad Ali. I doubt very much he would be willing to subject himself to the kind of fights he's gone through if he were to get the pay of an unskilled docker."

"Insofar as his actions in accord with his “social responsibility” reduce returns to stock holders, he is spending their money. Insofar as his actions raise the price to customers, he is spending the customers’ money. Insofar as his actions lower the wages of some employes, he is spending their money. The stockholders or the customers or the employes could separately spend their own money on the particular action if they wished to do so. The executive is exercising a distinct “social responsibility,” rather than serving as an agent of the stockholders or the customers or the employes, only if he spends the money in a different way than they would have spent it. But if he does this, he is in effect imposing taxes, on the one hand, and deciding how the tax proceeds shall be spent, on the other. This process raises political questions on two levels: principle and consequences. On the level of political principle, the imposition of taxes and the expenditure of tax proceeds are governmental functions. We have established elaborate constitutional, parliamentary and judicial provisions to control these functions, to assure that taxes are imposed so far as possible in accordance with the preferences and desires of the public — after all, "taxation without representation" was one of the battle cries of the American Revolution. We have a system of checks and balances to separate the legislative function of imposing taxes and enacting expenditures from the executive function of collecting taxes and administering expenditure programs and from the judicial function of mediating disputes and interpreting the law. Here the businessman — self-selected or appointed directly or indirectly by stockholders — is to be simultaneously legislator, executive and, jurist. He is to decide whom to tax by how much and for what purpose, and he is to spend the proceeds — all this guided only by general exhortations from on high to restrain inflation, improve the environment, fight poverty and so on and on."

"I have been impressed time and again by the schizophrenic character of many businessmen. They are capable of being extremely far‐sighted and clear‐headed in matters that are internal to their businesses. They are incredibly short sighted and muddle‐headed in mat ters [sic!] that are outside their businesses but affect the possible survival of business in general. This short sightedness is strikingly exemplified in the calls from many businessmen for wage and price guidelines or controls or incomes policies. There is nothing that could do more in a brief period to destroy a market system and replace it by a centrally controlled system than effective governmental control of prices and wages. The short‐sightedness is also exemplified in speeches by business men on social responsibility. This may gain them kudos in the short run. But it helps to strengthen the already too prevalent view that the ptirsuit [sic!] of profits is wicked and im moral [sic!] and must be curbed and controlled by external forces. Once this view is adopted, the external forces that curb the market will not be the social consciences, however highly developed, of the pontificating executives; it will be the iron fist of Government bureaucrats. Here, as with price and wage controls, business men seem to me to reveal a suicidal impulse."

"The political principle that underlies the is unanimity. In an ideal free market resting on private property, no individual can coerce any other, all cooperation is voluntary, all parties to such cooperation benefit or they need not participate. There are no values, no "social" responsibilities in any sense other than the shared values and responsibilities of individuals. Society is a collection of individuals and of the various groups they voluntarily form. The political principle that underlies the political mechanism is conformity. The individual must serve a more general social interest — whether that be determined by a church or a dictator or a majority. The individual may have a vote and say in what is to be done, but if he is overruled, he must conform. It is appropriate for some to require others to contribute to a general whether they wish to or not. Unfortunately, unanimity is not always feasible. There are some respects in which conformity appears unavoidable, so I do not see how one can avoid the use of the political mechanism altogether. But the doctrine of “social responsibility” taken seriously would extend the scope of the political mechanism to every human activity. It does not differ in philosophy from the most explicitly collectivist doctrine. It differs only by professing to believe that collectivist ends can be attained without collectivist means. That is why, in my book “Capitalism and Freedom,” I have called it a “fundamentally subversive doctrine” in a free society, and have said that in such a society, “there is one and only one social responsibility of business—to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say, engages in open and free competition without deception or fraud.”"

"The strength of the Friedman's critique of active policy does not lie in general principles or broad sweeps of history. It lies in the itemization of government failures: industrial regulation that is primarily in the interests of the special groups regulated, inefficient post offices, disappointing schools, welfare " messes," the failure of public housing. To some extent the Friedmans document these changes; to a greater extent they rely on current popular perceptions. These failures are in part real, and the Friedmans are not wrong in suggesting that the pursuit of social goals is very apt to be carried on much less efficiently than the pursuit of one's own self-interest. They do not question the theoretical need for internalization of externalities, as in pollution, but argue that the arrangements are bound to be inefficient (actually, they are rather muted on this particular argument, and nowhere flatly assert that the social gains do not exceed the costs). They are strongly opposed to testing drugs for efficacy but do not seem to question testing them for safety. In short, the critique tends to be selective, They are very ingenious at suggesting alternative policies for some problems, such as the voucher system for elementary education, the negative income tax to replace welfare, or the abolition of licensing for physicians. But when advocating comprehensive changes, it is important to consider the effects on the entire system."

"First, I think that his concept of freedom was much too shallow. The idea that low income is a restriction on freedom—something that I think is a fairly elementary point—is something he just never recognized. His idea of somehow equating the market with freedom, well, I don’t think they’re unconnected but to assume it’s a simple matter— as he seemed to assume—is to my mind disregarding the facts of life, and disregarding the values that are put on these ideas. Now Friedman did make some exceptions. He thought extreme poverty was a subject of government policy, but by and large I think this emphasis on freedom is misplaced because it has very little to do with the freedom of the individual, with the individual employee. It was the freedom of the employer, of a minority, that really he was pushing. I think freedom’s important. I certainly wouldn’t say freedom’s an unimportant matter. But the question is: What do you mean by freedom? Expanding the scope by which people can act is an important matter. And it was not just income transfers and other methods. I think Friedman let himself make rather absurd statements, like for example he opposed the licensing of physicians on the grounds that it was a restriction on freedom. So this is an illustration of how his narrow conceptualization of what freedom means led him to kind of absurd statements."

"Waiting his time in the 1960s and early 1970s was, however, perhaps the most influential economic figure of the second half of the twentieth century. This was Milton Friedman (1912- ) of the University of Chicago, later of the Hoover Institution on War, Revolution and Peace, a diligent, even indefatigable, advocate of the policy that was to fill the post-Keynesian void, especially in the English-speaking countries. A small, vigorously spoken man, uniquely determined in debate and discussion, entirely free of the doubt that on occasion assails intellectually more vulnerable scholars, Friedman was, as he remains, the leading American exponent of the classical competitive market, which he held still to exist in substantially unimpaired form except as it had suffered from ill-advised government intrusion. Monopoly, oligopoly and imperfect competition played no important part in his thinking. Friedman was a powerful opponent of government regulation and government activity in general. Freedom, he held, was maximized when the individual was left free to deploy his own income as he wished. On the other hand, Friedman, unlike less sophisticated practitioners of his faith, was not wholly indifferent to the freedom that accrues from having income to spend. To this end, he was the author of the most radical welfare proposal in the years following World War II. The income tax, he proposed, should, as always, diminish to zero as the lower income brackets are approached. And then in the lowest brackets it should return income, the amount increasing with increasing impoverishment. This was the negative income tax, a secure minimum income for all. Not many economists of the left could lay claim to such an impressive innovation. Friedman's central contribution to the history of economics was, however, his insistence on the controlling influence of monetary action on the economy and specifically on prices. After a lag of a few months, prices, he held, would always reflect movements in the money supply. So if one controlled the money supply limited its increase to the slowly expanding requirements of trade, the T in Fisher's historic equation prices would remain stable. In a statistically impressive demonstration, Friedman, in company with Anna Jacobson Schwartz, sought to show that this relationship had held, or appeared to have held, long in the past. So, presumably, it must in the future."

"Under Milton Friedman’s influence, the free-market ideology shifted toward unmitigated laissez-faire. Whereas earlier advocates had worried about the stringent conditions that were needed for unregulated markets to work their magic, Friedman was the master of clever (sometimes too clever) arguments to the effect that those conditions were not really needed, or that they were actually met in real-world markets despite what looked a lot like evidence to the contrary. He was a natural-born debater: single-minded, earnestly persuasive, ingenious, and relentless. My late friend and colleague Paul Samuelson, who was often cast as Friedman’s opponent in such jousts, written and oral, once remarked that he often felt that he had won every argument and lost the debate. As for relentlessness: Professor Friedman came to my department to give a talk to graduate students in economics. The custom was that, after the seminar, the speaker and a small group of students would have dinner together, and continue discussion. On one such occasion I went along for the dinner. The conversation was lively and predictable. I had a long drive home, so at about ten o’clock I excused myself and left. Next morning I saw one of the students and asked how the rest of the dinner had gone. “Well,” he replied, “Professor Friedman kept arguing and arguing, and after a while I heard myself agreeing to things I knew weren’t true.” I suspect that was not the only such occasion."

"Friedman came to Yale once and gave a talk called "Yale versus Chicago in Monetary Theory" before a house of 500 people. [...] It was quite interesting. I didn't get much involved at all in public, but we had a small private session afterwards. The thing I remember most about the occasion was that there was a very earnest, well-meaning graduate student who stood up at the big meeting and asked Friedman politely: "In your mode, money is the basic concept, and yet, you haven't ever told us exactly what money is conceptually. Could you help us understand it now?" Friedman cut the guy down in the withering way he can do by telling him that he didn't understand scientific methods. He said Newton didn't have to tell what gravity was; he only had to tell what it does. The same applied to money. That illustrates Friedman's methodology of positive economics which I think has done great damage. [...] You see that in Lucas, too. Their idea is the as-if methodology in which it is not a question whether the assumptions are realistic, but whether the results derived from the assumptions are consonant with the facts of observation. My reaction is that we are not so good at testing hypotheses so that we can give up any information we have at whatever stage of the argument. The realism of assumptions does matter. Any evidence you have on that, either casual or empirical, is relevant."
