Those who talk glibly about redistribution often act as if people are just inert objects that can be placed here and there, like pieces on a chess board, to carry out some grand design. But if human beings have their own responses to government policies, then we cannot blithely assume that government policies will have the effect intended.
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.
People in industry are not inert objects either. Moreover, unlike farmers, industrialists are not tied to the land in a particular country.
Russian aviation pioneer Igor Sikorsky could take his expertise to America and produce his planes and helicopters thousands of miles away from his native land. Financiers are even less tied down, especially today, when vast sums of money can be dispatched electronically to any part of the world.
If confiscatory policies can produce counterproductive repercussions in a dictatorship, they are even harder to carry out in a democracy. A dictatorship can suddenly swoop down and grab whatever it wants. But a democracy must first have public discussions and debates. Those who are targeted for confiscation can see the handwriting on the wall, and act accordingly.
