Yes, I suppose that's closer to where I was going, and I saw that you did address that, I guess I would extend that in saying I'm not sure that pre-imposing advantage and disadvantage to either groups is completely necessary. What I would say is that an overwhelming ideology of where one group "belongs" in the society relative to another can become a self-fulfilling prophecy over time, even if those groups weren't always inherently uneven (it helps if they are obviously). There were plenty in the south that believed that slavery and racial inequality was for "societal good" and that society wouldn't function if this wasn't maintained.
