White South Africans definitely. Black South Africans I don't know. Some of them could be better off financially but it's a heck of a thing to be treated as if you are a lesser being because of the color of your skin. I guess the answer is yes in regards to the economy, health (maybe, not sure sure on this) , government corruption and a couple other things but no on just the simple act of being treated like a human. Apartheid had to go but just throwing power into the mob was not a good way to do it. I don't have an answer as far as what would have been a better solution.
I left South Africa as a young teen during the collapse of Apartheid. We had a black maid / nanny who lived on our property in housing my parents provided for years. She did a lot of the work raising us as my parents were always at work. She had a daughter a couple years older than me. Years later my mom wrote her a letter to see how she was doing. She was completely destitute begging for money. Her daughter has multiple kids and was hiv positive. Really rough.
I really don't know what the right approach would have been. It's easy to be an armchair quarterback.
