Laws made by whom? Enforced by whom? The issue is always the humans in the system. You think the people fighting in the communist revolutions were fighting to implement something badly? It ended badly because they did not have any more of plan than you do. They were just wishing laws on paper would bind people. That people in power would protect the masses. But paper is just paper and those in power are always selfish. They have to be, to remain in power. Not understanding this is why they failed.
Capitalism does its best to try an make sure that greedy actions also result in benefits for society. It doesn’t always work. Where it doesn’t, we need to fight to regulate it. Minimal wages, workers rights, carbon tax, … Align the interest of the rich with the interests of society as much as possible. And in exchange for helping society, they get to be filthy rich. It is not perfect. It is not fair. But it works. You want to change things for the better, work on improving our regulated capitalism, instead of repeating extremist mistakes of the past. Because putting people in position of power and hoping they will do the right thing instead of the selfish thing will always fail. Capitalism is about exploiting selfishness for the greater good.
