Riverwalk that is a very big question.
Firstly, I'll quote John Lennon "Life is what happens to you while you're busy making other plans". Secondly, growing up as a young adult from an Afrikaner background, I never ever considered leaving my country (and there was no option for me to do so anyway). As a young mother, I became involved in a modest way in anti-apartheid activism, and believe me, my generation of all races thought we could - and fought to - change things from within. So no, we didn't consider emigrating then either.
My extended family of uncles and aunts were mostly academics (my mother dropped out of studying when she got married) and were way more progressive politically than my working class immigrant in-laws.
The harsh reality is that violent crime in South Africa is now endemic. "Put off" is my euphemism for being scared.
