Nor do the spokesmen for these organizations ever explain why, if the public school system is doing such a splendid job, it needs to fear competition from nongovernmental, competitive schools or, if it isn’t, why anyone should object to its “destruction.

I think that nothing is so important for freedom as recognizing in the law each individual’s natural right to property, and giving individuals a sense that they own something that they’re responsible for, that they have control over, and that they can dispose of.

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.

The majority does rule. But it is a rather special kind of majority. It consists of a coalition of special interest minorities. The way to get elected to Congress is to collect groups of, say, 2 or 3 percent of your constituents, each of which is strongly interested in one special issue that hardly concerns the rest of your constituents. Each group will be willing to vote for you if you promise to back its issue regardless of what you do about other issues. Put together enough such groups and you will have a 51 percent majority. That is the kind of logrolling majority that rules the country.

It's a moral problem that the government is making into criminals people, who may be doing something you and I don't approve of, but who are doing something that hurts nobody else. Most of the arrests for drugs are for possession by casual users. Now here's somebody who wants to smoke a marijuana cigarette. If he's caught, he goes to jail. Now is that moral? Is that proper? I think it's absolutely disgraceful that our government, supposed to be our government, should be in the position of converting people who are not harming others into criminals, of destroying their lives, putting them in jail. That's the issue to me. The economic issue comes in only for explaining why it has those effects. But the economic reasons are not the reasons.

To take a different example, whether it is less costly for loggers to use a chain saw or handsaw depends on the price of the chain saw and the handsaw, the amount of labor required with each, and the wages of different kinds of labor. The enterprise doing the logging has an incentive to acquire the relevant technical knowledge and to combine it with the information transmitted by prices in order to minimize costs.

What country in the world today engages in the most extreme anti-Semitic persecution? The Soviet Union. It’s not an accident, because if you have a society with concentrated power, if you have a collectivist society, it’s going to be in a position to exercise the preferences and prejudices of its rulers. Moreover, it’s going to have an incentive to do so, because it’s going to need a scapegoat and it will choose some group like the Jews or the blacks to be the scapegoat.
