A free man will ask neither what his country can do for him nor what he can do for his country.

There is no logical basis for the prohibition of marijuana. $7.7 billion is a lot of money, but that is one of the lesser evils. Our failure to successfully enforce these laws is responsible for the deaths of thousands of people in Colombia. I haven't even included the harm to young people. It's absolutely disgraceful to think of picking up a 22-year-old for smoking pot. More disgraceful is the denial of marijuana for medical purposes.

Statistics do not speak for themselves.

Theories can be based on any assumptions, however bizarre.

You can only make money if you buy a product, whatever it is - maybe a currency, maybe wheat and maybe something else - at a relatively low price and sell it at a higher price than you buy it at. There's no other way to make money.

Only a crisis - actual or perceived - produces real change. When that crisis occurs, the actions that are taken depend on the ideas that are lying around. That, I believe, is our basic function: to develop alternatives to existing policies, to keep them alive and available until the politically impossible becomes the politically inevitable.

I would say that in this world, the greatest source of inequality has been special privileges granted by government.
