Like later slave societies, modern society must deal with the opposite problem. It must maintain the order of scarcity in a society where resources are more and more abundant. It must conquer more and more of the human existence that is based on abundance. It must hold it's slaves in thrall when the chance of living fruitfully is all around them. The rulers of this society arose as capitalists.
Capitalists base their power on owning labor power.
They trace their origins to the mill owners of England. These rulers learned to pay workers for their labor power instead of simply taking the surplus grain of peasants. Capitalists need the order of scarcity to exist. Instead of owning slaves or peasants, they own the means of production that wage-workers work at. They maintain their power on top of our alienated activity.
