By encouraging men to spy and report on one another, by making it in the private interest of large numbers of citizens to evade the controls, and by making actions illegal that are in the public interest, the controls undermine individual morality.

The problem is that, in a world of floating exchange rates, as Italy was before the euro, if one country is subjected to a shock which requires it to cut wages, it cannot do so with a modern kind of control and regulation system. It is much easier to do it by letting the exchange rate change. Only one price has to change, instead of many.

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.

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 society based on the freedom to choose is better than a society based on the principles of socialism, communism and coercion.

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.

Japan has introduced fiscal stimulus five times in the past seven or eight years and each time it's been a failure and that's not a surprise. Fiscal stimulus is not stimulating in and of itself.
