I'm really not into communism, but I don't really think that capitalism is the answer. They both, in my mind, won't really work like the people who designed them wanted them to. The concept of the system might be perfect, I don't know, maybe it is, but when built, it's going to be lacking in someplace or another, because the materials, us, are flawed.
After all, even dictatorship would be just plain wonderful if we just found the right dictator.
Designing alternatives for existing systems is fun, but unfortunately (or not) it's quite hard to make one reality and see how it operates in practice.
