South African Migrants

I think I have heard the most convoluted argument ever to explain why South African Black Africans are rejecting the influx of Black Africans from countries to the north.

A professor, Chris Landburg from one of the universities in Johannesburg propounded the argument that "because of the Apartheid years" and the categorisation of people into groups with the White at the top, followed by the Indian and then Coloured people leaving the Black person, institutionally at the bottom of the pile. This segregation has continued to attached it's self in the Black Africans psyche as he or she, looks around for someone less able, they fix on the Black immigrant from the North as being an even lesser person and an easy outlet to vent his anger.

No mention of the economic situation or the local jobless person fearing that every extra immigrant dilutes the available work even more. 
Of course to do this would ask questions of the current government, much easer to raise the spectre of Apartheid as a 'back stop' for all the countries ills.
