I was last back there in 1999, on a business/holiday period of 3 weeks. And I do keep in contact with a few old friends.
SA has changed beyond all recognition since '94 when I left. Some things for the better, some for the worse.
Although a lot of people of more races have a lot more money and wealth today, there is still a lot that have nothing, mainly because they are uneducated and un-employable. Some I know, think that this may cause a Mugabe type situation where the white farmers are kicked off their land. If that happens there will be starvation and the economy will die, just as it did in Zimbabwe.
