Agreed, that’s why I put it in quotes. The way I should have worded it is that evolution has incentivized living things to act in a way that prioritizes their own survival over the survival of others. This is known as the survival instinct, or self-preservation, and is well established scientifically. This is a more appropriate argument against hierarchies of decision-making power than “human nature”.

I think they were specifically referring to Marxism-Leninism. It is “human nature” to act in your own self interest, so any system with hierarchies of decision-making power will eventually become corrupt. We just have to take a non-hierarchical path towards communism.

I pretty much just use 1337x.
