Genetic? Cultural is more likely. American blacks are mostly descended from Ibo and Ibibo from Biafra -- the best peoples in Black Africa, the market-dominant minority of the whole Gold Coast, a dynamic, energetic, ambitious group -- but they came down with a case of redneck-ism in their long stay in the South, and middle- or upper-class whites don't live among rednecks any more than they live among blacks. You see a lot of white-on-white conflicts that look almost exactly like white-on-black ones wherever hillbillies and non-hillbillies try to coexist -- particularly in the southern Rust Belt, where it's common for Catholic ethnics to be the middle class and hillbillies/rednecks the former factory hands. I'd recommend reading _Hillbilly Elgy_, Thomas Sowell's _Black Rednecks and White Liberals_, and of course _Albion's Seed_ for details. Jim Webb also had some essays on this subject, before he was elected to Congress; he had plans to unite hillbillies and blacks as a single interest group, and I'm not sure if that would have been a good idea or a bad one.
