Had several South African families in my little suburb in Northern Virginia when I lived there. (For whatever reason, several SA firms were leaders in IP security systems). As one of them explained to me, ‘if you’re white, there is no future for you in South Africa’. I suppose those who have stayed have done so either because South Africa is their home and they refuse to leave, or they can’t.
....But in the end, they will have no choice but to leave.
