The nomadic "primitive" people today usually aren't hunter-gatherers, but pastoralists - that's what a lot of the African tribes that remain out of civilization do, they herd cattle and that is a marker of prestige and status. They're still tribes without a very clear political hierarchy or classes as such, but there is wealth, status, and competition.
Usually the hunter-gatherer band was egalitarian because there were too few members to create a division of labor, and no way to enforce it, and such a construct would have been counterproductive. It was never a natural proclivity or some sort of ideology that was imposed on them (who would impose it?) Egalitarianism made sense in that place, and continued to make sense to the laboring classes for a long time. Anything that broke them into grades of civic worth and told them to attack each other on that basis only weakened their position, and so this "contradiction" was provoked violently and with trained influencers and agentur insinuating ad nauseum, and then mandating it in state education, that you're supposed to be with your caste. But, that situation where workers could form associations, and where workers had access to written knowledge and could become scientists, was also an adaptation to that time and place.
Caste is the human "mean" in civilization, because it is rooted in the aristocratic view of thought itself, and how the mind and its processes would be segregated. Absent anything restraining it, humans default to the same sort of organization, whether it is the tripartate version or the five-caste version which subsumes the whole society and locks in the lower two castes. They really don't know anything else, and when people have these ideas of the "true form" of civilization, they always in one way or another revert to a caste system, because they have already regimented their thinking to value the primordial betrayal above all else, and regard property as superior to commerce in whatever form it takes. The interests of labor are always dismissed, and the lowest class is defined specifically as a suffering class to remind everyone what this really was about. Humans love kicking down too much to ever give that up, and anything that doesn't do this is considered an imperfection in the "default" mind. The only people who ever really wanted it to be different were in the lowest class, because everyone else in the end is beholden to play this game if they don't want to be lumped with the lowest class. There are the rare people who have nothing to lose and strike a blow against aristocracy, knowing that their cause was always doomed by the end, but humans really went out of their way to uphold this caste view even though it served no genuine function and has been ruinous every time it has asserted itself. We were trained to not think it was the "mean" because human societies have never been particularly stable and were often forced to mitigate this quality since caste society is ruinous for any protracted struggle. The moment it became possible to enclose the world, humanity returned to its typical behavior - caste, aristocracy, viciousness, and cruelty for no reason. That's what humans are.
