One think I would like to say about the current 'communist' states, is that they in fact are no longer even a huge perversion of communism they are in fact the ultimate form of capitalism. There is a small group of people who control all of the countries assets and they can keep people from over taking them because they have all the power. This is what would happen if Capitalism was to reach its ultimate potential one group would take control one way or another and it would become a world much like Korea and China. Though at first there would be a point in time where prices would be insanely high and there would be a large amount of death in the lower classes because there would be a large lack of jobs and affordable anything after a while this would 'stabilize' and fall into what is called 'Communism'
