An old one, but a good one nonetheless. Economics made easy, with cows.
SOCIALISM: You have two cows. The State takes one and gives it to your neighbour.
COMMUNISM: You have two cows. The State takes both and gives you and your neighbour some of the milk.
FASCISM: You have two cows. The State takes both and sells you and your neighbour some of the milk.
BUREAUCRACY: You have two cows. The State takes both, shoots one, milks the other, and then throws the milk away.
NEO-LIBERAL CAPITALISM: You have two cows. You sell one and buy a bull. Your cow has calves. The State takes one of the calves and gives it to your neighbour.
LIBERTARIANISM: You have two cows. What you do or don’t do with your cows is your own damn business.
