Because its the system we use, and, more importantly, it works. The Cold War was Communism vs. Capitalism, not truly an armed conflict so much as a competition on who can be more sucessful. In short, capitalism won, as America Demonstrates by being a dominant economic power, even China has adopted a kind of government run capitalism(its wierd nyoro~) and its growing exponentially(that and they cheat with a fixed currency rate, the cheaters) Capitalism isn't perfect, but it is the most sucessful method in history as of now (im not to clear on the European Socialism vs. true socialism thing, im acting under the impression that Europe blends the two nyoro~) and thats why Capitalism is good!
