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.

A free society releases the energies and abilities of people to pursue their own objectives. It prevents some people from arbitrarily suppressing others. It does not prevent some people from achieving positions of privilege, but so long as freedom is maintained, it prevents those positions of privilege from becoming institutionalized; they are subject to continued attack by other able, ambitious people.

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.

The proper role of government is exactly what John Stuart Mill said in the middle of the 19th century in "On Liberty." The proper role of government is to prevent other people from harming an individual. Government, he said, never has any right to interfere with an individual for that individual's own good.

See, if you look at the drug war from a purely economic point of view, the role of the government is to protect the drug cartel. That's literally true.

We economists don't know much, but we do know how to create a shortage. If you want to create a shortage of tomatoes, for example, just pass a law that retailers can't sell tomatoes for more than two cents per pound. Instantly you'll have a tomato shortage. It's the same with oil or gas.

It all would have been much better if individuals saved for their own old age.
