"These skills and these jobs in the labour market are the backbone of the world. We cannot and should not educate ourselves out of these jobs. Who will empty my bin or yours?"
So, because the black Africans have been doing these jobs for years, they should be forced to continue doing them by preventing them from attending higher learning institutions?
Why not let white people choose to do these jobs? Some will. Once upon a time, before white people went to Africa, there were black Africans who were "doctors" and chiefs and some variety of traditional "lawyer" and kings and merchants and farmers and of course garment makers and cleaners. So why should they be restricted to less than the full variety of jobs just because whites moved to Africa and took the top tier?
