In order to progress from the "communist" tribal nature to a "capitalist" system, you need to have people who have more money than they could produce with their own labor.

In the annals of human history, this has meant one thing - conquer another tribe and enslave the survivors. Thus, you and your buds get out of working for a living.

Go far enough back in any "elite" bloodline, whether noble or wealthy, and you'll find warlords. A government has its basis in a bunch of guys with swords who sat down and said - "You guys give us food, and we'll protect you from the other guys with swords who want your food."
