As a felloiw South African, I can tell you that his schooling was of the elite kind. I also went to one, so I know exactly what they cost and how much parents had to be taking home to afford that. If you read wiki (I think it's wiki), he boasted of the amount of money his family had.

Those schools give you connections that enable you to find angels later in life, which is exactly what he did. It wasn't hard work. He was well connected.
