We had much freer trade in the 19th century. We have much less globalization now than we did then.

Adam Smith's key insight was that both parties to an exchange can benefit and that, so long as cooperation is strictly voluntary, no exchange can take place unless both parties do benefit.

Our minds tell us, and history confirms, that the great threat to freedom is the concentration of power. Government is necessary to preserve our freedom, it is an instrument through which we can exercise our freedom; yet by concentrating power in political hands, it is also a threat to freedom. Even though the men who wield this power initially be of good will and even though they be not corrupted by the power they exercise, the power will both attract and form men of a different stamp.

As a nation, we have been responsible for the murder of literally hundreds of thousands of people at home and abroad by fighting a war that should never have been started and can be won, if at all, only by converting the United States into a police state.

I think almost every economist would agree that government gets itself in trouble when it tries to interfere with voluntary behavior.

In the current world, with the skills needed, dropouts [like no secondary education] are condemned to being members of the underclass. In my view, this is a fault of the American school system, which is a government monopoly.

The most unresolved problem of the day is precisely the problem that concerned the founders of this nation: how to limit the scope and power of government. Tyranny, restrictions on human freedom, come primarily from governmental restrictions that we ourselves have set up.
