The liberal conceives of men as imperfect beings. He regards the problem of social organization to be as much a negative problem of preventing 'bad' … - Milton Friedman

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.”

If we have system in which government is in a position to give large favor - it's human nature to try to get this favor - whether those people are large enterprises, or whether they're small businesses like farmers, or whether they're representatives of any other special group. The only way to prevent that is to force them to engage in competition one with the other.

"We now know, as a few knew then, that the depression was not produced by a failure of private enterprise, but rather by a failure of government in an area in which the government had from the first been assigned responsibility — -"To coin money, regulate the Value thereof, and of foreign Coin," in the words of Section 8, Article 1, of the U.S. Constitution. Unfortunately, as we shall see in Chapter 9, government failure in managing money is not merely a historical curiosity but continues to be a present-day reality."
