Are we as a species incapable of an equitable social system?

[jpgray]

It seems no matter what sort of system or laws we create, the few always seem to be able to manipulate it into the familiar form: the haves and the have nots. Part of the problem is that some are so ambitious they will not stand for equality with those who are less ambitious, and those who are less ambitious are too sanguine about giving up their rights and property to authority figures. Is there a social system that can trump this seemingly natural tendency of humans to divide into the meek and the exploitative? Or is this tendency simply the result of cultural indoctrination and inertia resulting from a long history of inequitable systems?

And yes, this thread can stand in for a Sophomore dormitory. :D
