What is your opinion about Communism?

It seems to me that every communist system, even proto-communist systems going back to the peasant revolts of medieval Europe that wanted to abolish private property result in the same thing, power concentrated in one person. It seems to me that every system but democracy ends up this way.

Also I disagree that it's a good idea in theory. What is a good idea if it doesn't actually work? That's called a bad idea.
