The Fed was largely responsible for converting what might have been a garden-variety recession, although perhaps a fairly severe one, into a major catastrophe. Instead of using its powers to offset the depression, it presided over a decline in the quantity of money by one-third from 1929 to 1933 ... Far from the depression being a failure of the free-enterprise system, it was a tragic failure of government.

The major basis for my opposition to marijuana prohibition has not been how badly it's worked, the fact that it's produced much more harm than good - it has been primarily a moral reason: I don't think the state has any more right to tell me what to put into my mouth than it has to tell me what can come out of my mouth.

A society that puts equality - in the sense of equality of outcome - ahead of freedom will end up with neither equality or freedom. The use of force to achieve equality will destroy freedom. On the other hand, a society that puts freedom first will, as a happy by-product, end up with both greater freedom and greater equality. Freedom means diversity but also mobility. It preserves the opportunity for today's less well off to become tomorrow's rich, and in the process, enables almost everyone, from top to bottom, to enjoy a richer and fuller life.

The important issue is not how much inequality there is but how much opportunity there is for individuals to get out of the bottom classes and into the top. If there is enough movement upward, people will accept the efficiency of the markets. If you have opportunity, there is a great tolerance for inequality. That has been the saving grace of the American system.

There's no such thing as a free lunch.

My interest in political philosophy was rather casual until I met Hayek.

Socialism, in the traditional sense, meant government ownership and operation of the means of production. Outside of North Korea and a couple of other spots, no one in the world today would define socialism that way. That will never come back.
