You know what's funny about Communism? It's exactly like Capitalism, except that you have just one person in charge of things. (Or one group.) It's what would happen if you ever had just one corporation in the whole economy. Especially in a political system like the U.S.'s, where money and speech are interchangeable.
The problem with capitalism isn't who's in control. There's no such thing as a benevolent dictator. Capitalism is slighty better than Communism, I suppose, since at least you've got more than one dictator, and anyone can (hypothetically) become a dictator. But it still doesn't solve the problem, which is the dictators telling people what to do.
