There are severe limits to the good that the government can do for the economy, but there are almost no limits to the harm it can do.

It is taken for granted that workers should receive their pay partly in kind, in the form of medical care provided by the employer. How come? Why single out medical care? Surely food is no less essential to life than medical care. Why is it not at least as logical for workers to be required to buy their food at the company store as to be required to buy their medical care at the company store?

So long as large sums of money are involved - and they are bound to be if drugs are illegal - it is literally impossible to stop the traffic, or even to make a serious reduction in its scope.

Italy may well be the main problem. It has benefited most from the euro by having been able to get the euro interest rate instead of what otherwise would have been its own. That would be much higher because Italy has been accumulating so much debt. In the past, Italy has inflated away its debt. The virtue of the euro is that Italy can't do it alone. A tight ECB policy wouldn't permit that to happen again.

The power to determine the quantity of money... is too important, too pervasive, to be exercised by a few people, however public-spirited, if there is any feasible alternative. There is no need for such arbitrary power.

The countries that have risen and separated out as a result of the collapse of the Soviet Union are, on the whole, following freer economic policies. Most of these states have freer government and less restrictions on trade.

The same thing will happen in China that happened in Chile. Political freedom will ultimately break out of its shackles. Tiananmen Square was only the first episode. It is headed for a series of Tiananmen Squares. It cannot continue to develop privately and at the same time maintain its authoritarian character politically. It is headed for a clash. Sooner or later, one or the other will give.
