Just as any rational person could have predicted that "Democracy" in the middle east would immediately result in the election of a "Theocracy", so too could any rational person predict that "Democracy" in an African nation with a lopsided majority of Blacks and a minority of Whites would end up as a Crony Socialist revenge scheme against the Whites.
Hell, even Mandela could see that coming, and tried to stave it off somewhat.
For decades, people in RSA claimed that all hell would break out, once Mandela died. Actually, it broke out after about 1 year, or so, with Nelson in power.
Mandela saw it very clearly when he warned that a South Africa without whites would be a South Africa without doctors, teachers, etc.; like the US, South Africa has to come to terms with how to address relations between the people who create, maintain, and pay for everything, and those who primarily eat, sleep, and breed. Like the US, there is an economic angle to this that is ignored in favor of a more flashy racial angle.
