Ideologies: Why so many don't work
I think this does a good job of describing ideologies and what happens under them.
FEUDALISM: You have two cows. Your lord takes some of the milk.
PURE SOCIALISM: You have two cows. The government takes them and puts them in a barn with everyone else's cows. You have to take care of all the cows. The government gives you a glass of milk.
BUREAUCRATIC SOCIALISM: Your cows are cared for by former chicken farmers. You have to take care of the chickens the government took from the chicken farmers. The government gives you as much milk and eggs as they say you should need.
FASCISM: You have two cows. The government takes both, hires you to take care of them, and sells you the milk.
PURE COMMUNISM: You share two cows with your neighbors. You and your neighbors bicker about who has the most "ability" and who has the most "need." Meanwhile, no one works, no one gets any milk, and the cows drop dead of starvation.
RUSSIAN COMMUNISM: You have two cows. You take care of them but the government takes all the milk.
CAMBODIAN COMMUNISM: You have two cows. The government takes both and shoots you.
DICTATORSHIP: You have two cows. The government takes both and drafts you.
PURE DEMOCRACY: You have two cows. You and your neighbors decide who gets the milk.
REPRESENTATIVE DEMOCRACY: You have two cows. You and your neighbors pick someone to tell you who gets the milk.
BUREAUCRACY: You have two cows. At first the government regulates what you can feed them and when you can milk them. Then it pays you not to milk them. Then it takes both, shoots one, milks the other and pours the milk down the drain. Then it requires you to fill out forms accounting for the missing cows.
CAPITALISM: You have two cows. You sell one and buy a bull. Then you have many cows and lots of milk to sell.
PURE ANARCHY: You have two cows. Your neighbor, who's cows died, sneaks over to your house, kills you, and takes your cows.
LIBERTARIANISM: You have two cows. You milk them and drink the milk. Your neighbors try to take the milk, you kill them. The government congratulates you.
