I get what you're saying, perhaps too far of a generalisation in my statements; I have been, of course, raised with Western values/modern values. Do I know anything about African culture? Not really; it's pretty much dead where I live.
I am a descendant from a now long and forgotten tribe here, Khoi san, they were pretty much nomads, so I doubt they had a need for classes.
I am sure in the deeper parts it may still be alive, but that's not to say there were tribes without class structures, it may have been less hierarchical, but from the top of my head, Zulus here have Kings/Royalty, they had a military who obviously carried more favour than a herder of cattle/farmer. I do think perhaps the class divides were flatter, and I think that does make for a calmer society, but I don't see it as totally non-existent.
I obviously don't know how other cultures work, but the one that we've chosen to use moving forward in modern times is the one I am drawing from and one that has built itself on classes and hierarchy.
Not saying either is right or wrong; I think we should all be able to choose which one we like best and congregate around that, which is to me not the case; we all pushed to accept one. I never want to tell people what to do, I just want to ensure they have the choice
