We live in capitalism. Its power seems inescapable. So did the divine right of kings. Any human power can be resisted and changed by human beings. Resistance and change often begin in art, and very often in our art, the art of words.
I'm now curious as to how you and seemingly 5 other people know what the rich taste like. You guys had a BBQ and didn't invite the rest of us, didn't you?
I mean, yes and no. There's biology that drives human behavior, as much as we want to pretend otherwise and physics are responsible for scarcity.
Given our biological programming and scarcity of resources there isn't an economic system that can "be fair and equal" at any scale beyond hunter gatherer tribes.
