Economics has become increasingly an arcane branch of mathematics rather than dealing with real economic problems.

Freedom is a rare and delicate plant. Our minds tell us, and history confirms, that the great threat to freedom is the concentration of power.

The invisible hand in politics operates in the opposite direction to the invisible hand in the market.

Consider Social Security. The young have always contributed to the support of the old. Earlier, the young helped their own parents out of a sense of love and duty. They now contribute to the support of someone else's parents out of compulsion and fear. The voluntary transfers strengthened the bonds of the family; the compulsory transfers weaken those bonds.

I want people to take thought about their condition and to recognize that the maintainence of a free society is a very difficult and complicated thing and it requires a self-denying ordinance of the most extreme kind. It requires a willingness to put up with temporary evils on the basis of the subtle and sophisticated understanding that if you step in to do something about them you not only may make them worse, you will spread your tenticles and get bad results elsewhere.

The lesson for Asia is; if you have a central bank, have a floating exchange rate; if you want to have a fixed exchange rate, abolish your central bank and adopt a currency board instead. Either extreme; a fixed exchange rate through a currency board, but no central bank, or a central bank plus truly floating exchange rates; either of those is a tenable arrangement. But a pegged exchange rate with a central bank is a recipe for trouble.

Because it is one thing to have free immigration to jobs. It is another thing to have free immigration to welfare. And you cannot have both. If you have a welfare state, if you have a state in which every resident is promises a certain minimal level of income, or a minimum level of subsistence, regardless of whether he works or not, produces it or not. Then it really is an impossible thing.
