The Bifurcation of South Africa's Black Community

30 years after the end of apartheid, in what ways is South Africa's black community allegedly disadvantaged groups still or has the group itself been bifurcated into privileged and oppressed subgroups? I mean the important thing to say is that South Africa is an overwhelmingly black nation, society and state. According to the recent census it was 80 percent black. So to speak of black South Africans as a group is a rather odd way of formulating it.
