This is an excellent question IMO, and I’m sure you’ll receive plenty of excellent (and energetic) responses, but I do want to point out something which chronically gets overlooked, as part of these discussions. Ready?

Homo sapiens is traditionally a tribal, social, and clan-based animal, not unlike our cousin chimpanzees, and others such as wolf & dog packs, elephant herds, parrot flocks, and a couple other examples. Our organisation upon such likely goes back at least 2.4Myrs, when biologists and those in related fields first classified “Homo” as a distinct genus. But arguably, such goes back perhaps as long as our common ancestor of chimps, maybe 7Myrs ago or so. Or earlier!

My point is– modern humans’ natural state is to exist in smallish, commune-like situations, and that is a fact. That’s literally in our DNA upon a multitude of levels, and literally spans the entire length of H. sapiens ~300Kyr history.

Meaning? That we’re naturally communists of a kind, and my take on “socialism” is that it’s roughly an attempt to make our traditional style work, when organised upon regional and national levels.

THAT SAID: I think it’s good to also observe how things happen in the wild. For example, my mentors Robert Sapolski and Jane Goodall famously observed our fellow apes & monkeys being total assholes towards each other, amidst hierarchy-type situations. It’s a complicated discussion, anyway, and maybe not hard to imagine why so many of our fellow rich, needy, powerful human monkeys are such total, narcissistic assholes towards everyone else.
