You say that whites are on their own, which is probably true. But you imply that whites will be left alone. I disagree, once black rule starts to fail and they need a scapegoat, they will blame whites.
And their fate will be the same as all scapegoats in totalitarian regimes.
Actually, I agree with you. Whites are, by and large, an unappreciated minority in SA. And the income disparity between white and black is a constant problem that will prove a big temptation for black government to try to 'fix' through wealth redistribution. The whites are a soft target.
