I'm not trying to deny the (until very recently legally enforced) class difference between whites and blacks in South Africa, nor the social issues causing hiring discrepancies in the States.

However, it's not a narrow reading of events. Musk is African. Head a bit out of the way in South Africa and you'll find white kids who spend all day running around with black friends with the whole group speaking fluent Zulu. They've grown up there and their families have been there for generations.
