Not entirely true. In Australia, and North and South America (I don't know enough about other indigenous populations to list more nations), First Nations were mostly egalitarian but battled over natural resource scarcity. The history we're taught is told through a white-male capitalist perspective, and it's very misleading. Native American tribes were not savages who randomly killed each other.

There are leavers and takers. The takers want everything while the leavers aren't interested in conquering - leavers fish to feed themselves, their family, and maybe the community. Essentially, takers are capitalists who imprison themselves to work and money, and leavers are liberated.
