Yeah, but nothing is perminant, (or permanent). All hierarchies are temporary because everything is temporary.

Aristotle discussed a then-current idea to redistribute all personal wealth above 5x the poorest citizen

People have come up with ideas since forever. I'm sure the first philosophy on the redistribution of wealth was "Unga bunga, bunga unga bunga!" The problem is putting those ideas into practice. So far, when people try to eliminate hierarchies, the result is that someone comes in and takes advantage of the people who don't think there's a hierarchy.

Humanity itself may be temporary, but it seems like the idea of hierarchies will outlive humanity.
