Those South African blactivists are now howling as their hostages escape, because they know that when the last ones are gone the continuous power outages and infrastructure failures will become permanent.
Mandela offered concessions to the whites to stay, because he openly stated they’d have no doctors, teachers, engineers, etc. - and those concessions evaporated when he died and the new black kleptocrats in political office robbed the population and didn’t invest in maintaining anything.
Soon they’ll be baking mud pies like Haitians...
But you left out potable water, which they do NOT have any of now, only partly due to the droughts, but because they got rid of ALL of the whites!
It's hard to believe now, but in his early years in power, the late Robert Mugabe mostly left the white farmers in Zimbabwe (formerly Rhodesia), because, like Mandela, he was intelligent enough not to kill the goose that lays the golden eggs. Mugabe's main focus while in power (other than large-scale graft) was to settle scores with enemies from other tribes.
When his mismanagement of the country created enough public unrest that his rule was in jeopardy, Mugabe realized that he needed both a scapegoat and at least a short-term way of buying the loyalty of his people, so he adopted a campaign of terrorizing and displacing white farmers and handing their land over to his loyalists, who of course ran the farms into the ground within months.
The same scenario is gradually playing out in South Africa.
