I've got to tell you that my experience of South Africans that I came across in real life and on forums is that they were awfully glad to get out of SA with their lives. They complain about having to live in guarded enclosures, and worry about the risk every day of being raped, mugged or car jacked.

I suspect most SA ex pats you speak to will give you similar reasons for their move, which I guess might not be what your editor wants to see in a story
