A great hunter, let's say, might become a leader in a hunter gatherer group. But part of what makes him a great hunter is the fact that he shares. And that's also to his ben because then if someone else huntsn is successful, he gets his share. A complex human hierarchy is sustainable without reciprocity. The revolutionary marxis types an take that fundamental truth, which is that sometimes it's time for a revolution. They're so they're just wrong. It's just not the case. When a hierarchy, he degenerates, then it becomes based on power. Any hierarchy, it could be a creative hierarchy, it can be a competency hierarchy.
