Capitalism is the "opposite" of communism. Socialism is the combination of both.Both socialism and communism have appeared and died in less than 100 years. Other forms of society exist (fiefdoms, tribal organizations, religous compounds, etc...). If you examine the history of the world, and keep in context the knowledge and education of the people during different times, the progreession of societies from "survival of the fittest" to our current structure (taken as a whole) is both logical and natural. One can argue that the more knowledgeable and educated a society is, the less likely it will be misled and duped by those who have superior education (or at least an understanding of the current needs of the society).
Given this, Capitalism is a superior system.
