We need each other to do things that we can't do for ourselves. If we are intimately connected with each other, we just give things to each other; if we don't know each other we find another way to handle it. If you think about it, each according to his or her abilities and each according to his or her needs is sort of the same thing as supply and demand.
David GraeberIf you look at history, there seems to be a regular pattern: the country with the most powerful military also happens to be the one with the world trade currency. That gives them an enormous economic advantage, which causes goods to flow into their country.
David GraeberYou can't have cutthroat competition when there's no one stopping you from actually cutting each other's throats. In order to build up trust we also have to think about each other's needs and it creates an entirely different dynamic.
David GraeberThe notion that a society could be regulated entirely by market forces is a utopian fantasy: an impossible dream generated by imagining what the world would be like if everyone's behavior was utterly consistent with some abstract moral ideal-in this case, economic theories that assume all human action is based on calculating, systematic, (but scrupulously law-abiding), greed.
