>I am pretty sure that it is a political goal not an economic one, this is obvious considering US black literacy levels took until 1979 to be comparable to whites.
I don't follow. 1979 would have been a high point in closing the black/white economic gap in America (partly because of the falling economic prospects of white Americans at the time).
Over here education came first economics later, that will color my conclusions. I am pretty sure giving black people as little education as possible was a political goal in the US.
