How has racial differences between black and white citizens affected politics in South Africa since pre-1994 till now?

South Africa's recent political history has effected most
by decades of apartheid.  The word "apartheid" literally means "apartness," which sums
up the political interactions between blacks (and coloureds) and whites.  Blacks had
very few rights during apartheid.  They could not vote, attend white schools, or even
marry outside of the Christian Church.  Whites received the best jobs, education, and
land.  Because of the efforts of Nelson Mandela and the African National Congress, black
South Africans eventually received the same rights and opportunities as whites. 
Unfortunately, the socioeconomic status of blacks will take decades to match whites. 
The question for politicians today is:  How to "bridge the gap" without throwing the
country into political or economic chaos.  A challenge, indeed.
