I am currently reading The Black Book of Communism edited by Stephane Courtois. This is the cure for any lingering romanticism about communism. Courtoise and 10 other scholars offer a country-by-country accounting of the cruelty, terror, human waste and castastrophe (the body count exceeds 100 million.)
Socialism: You have two cows. You give one cow to your neighbor.
Communism: You have two cows. You give both cows to the government with the false hope that they might give you some milk.
Fascism: You have two cows. You give all of the milk to the government and the government sells it.
Nazism: You have two cows. They are found not to be Aryan cows. The government shoots you and places the cows in a labor camp.
Anarchism: You have two cows. You keep both of the cows, shoot the government agent and steal another cow.
Capitalism: You have two cows. You sell one cow and buy a bull.
Surrealism: You have two giraffes. The government makes you take accordion lessons.
