"Humans need leaders."
And we pick such good ones, Pol Pot, Stalin, Lenin, Hitler...
The only was for communism to work is for everyone to be totally honest, totally dependable, un-selfish and of general good will. In other words, their ain't many humans like that. Maybe if we had a hive-mind like the ants.
I've had a real life minor experience with socialism once, back in college. At the time, I was living in a fraternity house, and the "house parents" said, "look, you've got all 10 people living here, you've got 10 cartons of milk in the refridgerators, you've to 10 loaves of bread, cartons of eggs, 10 sets of condiments, etc... Why not combine resources, and we'll just share. Think about how much money everyone will save, and how we'll be able to have meals together, and life will be good..." Anyway, we all agreed to give it a try, and it lasted exactly two weeks. First off, we weren't saving any money. Secondly, the "house parents" were buying cheap stuff (like house brand ketsup, not the real thing, Heinz), and didn't have anywhere near as much as we expected. We all suspected these "house parents" of pocketing more than a little of the money. There were shortages of pretty much everything, and they would up with a full scale rebellion on their hands. Like I said, it lasted all of two weeks.
I read somewhere here on FR that socialism is simply the equal distribution of misery.
