Actually we've had a black bourgeoisie or the makings of a black bourgeoisie for many more decades.In a sense the quest for the emancipation of black people in the US has always been a quest for economic liberation which means to a certain extent that the rise of black middle class would be inevitable. What I think is different today is the lack of political connection between the black middle class and the increasing numbers of black people who are more impoverished than ever before.
