South Africa had a reputation of mistreating blacks until their president experienced an epiphany and instituted equal treatment for all. Their defense department even ended their nuclear weapons program. Some thanks they got. South Africa's crime rate has exploded (especially rape).
As a historic note, blacks and whites arrived in southern Africa at about the same time. Only the pygmies were original settlers. No one stole land from anyone. I'd suggest that whites sell what they can, plant salt in the fields and burn the rest -- Atlas Shrugged. Australia is looking for immigrants if they have certain skills like farming and wine making.
Wonder how many years until the South African population is starving like Zimbabwe and Venezuela. With an example next door to them, one would think they would learn.
