Karl Marx, the chief founder of communism
Does communism cause poverty? And how can this be tested?
Karl Marx
What counts as "testing"?
The short answer is "yes": it does cause poverty. But as far as testing goes, it depends on how you define "test." When hearing the word "experiment," most people have the mental image of a laboratory; but I should acknowledge in advance that experiments are hard to do in economics and politics. Even the possible ones usually require major government actions which may be unpopular, and people generally don't like to be guinea pigs. This is true of any experiment about whether communism has negative effects on prosperity.
Karl Marx
The experiments that no one wanted ...
So is there such an experiment? It turns out that there are two on a large scale, but not ones initiated by any government or university. They are natural experiments, or ones in which "the experimental and control conditions are determined by nature, or by other factors outside the control of the investigators." (source citation) While they were set in motion by human beings rather than nature, their purpose was not experimental at all; but the result of complicated political negotiations following a major war. Both sides in these negotiations - who had been allies during this war - would have preferred that their own system of government be established in the territories of their former enemies; but neither had the military power to do so for all those territories. The result was a compromise, which began two of the most epic natural experiments in the history of economics - two experiments neither side wanted, but which both sides got; and which clearly show a causal relationship between communism and poverty.
