Redistribution that works

From Thomas Sowell remarks in 2012:

The history of the 20th century is full of examples of countries that set out to redistribute wealth and ended up redistributing poverty. The communist nations were a classic example, but by no means the only example.

In theory, confiscating the wealth of the more successful people ought to make the rest of the society more prosperous. But when the Soviet Union confiscated the wealth of successful farmers, food became scarce. As many people died of starvation under Stalin in the 1930s as died in Hitler’s Holocaust in the 1940s.

How can that be? It is not complicated. You can only confiscate the wealth that exists at a given moment. You cannot confiscate future wealth — and that future wealth is less likely to be produced when people see that it is going to be confiscated. Farmers in the Soviet Union cut back on how much time and effort they invested in growing their crops, when they realized that the government was going to take a big part of the harvest. They slaughtered and ate young farm animals that they would normally keep tending and feeding while raising them to maturity. . . .

Knowledge is one of the few things that can be distributed to people without reducing the amount held by others.
