Okay, so let's say that "eating the rich" wasn't the problem. Then what was? Corruption in the government? Who would have thought that a government that disowned and deported people by the trainload would turn out to be corrupt? suprised_pikachu.jpg
Same thing happened in China BTW. People were starving in front grain depots filled to the brim because the government had sold much of it abroad in order to create the appearance that their plans were working out perfectly. I think the moral of the story is likely that you can't murder your way to a fair and just society.
Yet for some reason, people keep thinking that if only they put the right person in charge, things would be different the next time and it would work out for sure. Which is funny, because Stalin, Mao, and Pol Pot all shared the same belief — that they had figured out the secret sauce of how to make communism work.
And no, I'm arguing that unrestrained capitalism is the answer either, but rather, that a mix of capitalism and socialism that dominates much of the world, even if imperfect, appears to be the best we can do. If you look at successful "communist" countries like China or Vietnam, you'll find that they both adopted elements of capitalism into their economies, and they weren't doing all that great until they did.
Basically, there has to be an element of risk and reward, because people don't make an effort if there's nothing for them to gain (yes, that's the old joke that communism doesn't work because nobody works under communism). People will always strive to maximize personal gain. If they can't make more money by working more, they'll make more free time by working less, unless you punish them for slacking off, in which case you've just created forced labor. See, no matter how you try to approach this, you can't force people not to be selfish without tyranny. It's been tried time and time again and it always ended in bloodshed.
Correct me if I'm wrong, but I was under the impression that violent revolution is exactly what Marx said was essential in order to bring about the communist utopia he envisioned. That's precisely why communism has such a bad rep among anyone but edgy teenagers and college students. Are you telling me Marx was wrong about this? If so, please elaborate.
