I don’t know that South Africa has gotten as bad (yet); the blacks were begging the whites to stay in South Africa, as without them they literally had no schoolteachers, doctors, etc.
I believe that is why more whites in South Africa are better off than in Zimbabwe; the black ruling class realizes that without them (at least for the time being) the country is doomed. The events on their northern border can demonstrate that for the black ruling class in SA better than anything else could; Zimbabwe’s problems are spilling across the border, and black South Africans are beating the immigrant horde back.
I was in Zimbabwe in the mid 80s. The Rhodies then were seeing the handwriting on the wall. A lot of them got out. The Anglos headed back to Blighty or to Australia or NZ. The Boers went back to South Africa. They were all trying to unload whatever they could just to get enough hard currency to bail. The currency of choice was the Kruegerrand, solid gold. Poor sods. They and their forefathers had invested everything in Rhodesia and it worked. Then along came “uhuru.”
I wish those farmers good luck and hope that they would take 2 of each species of animal with them when they get on the boat...
