If he's doing it all for money and to live a life of luxury then why does he live in a 50k house in Texas? Yes he had a McLaren F1, so what? That was a long time ago when he was young. He drives a model S these days.

If he's doing it all for money then why start the companies he did? All of them are helping to solve a problem for mankind. He didn't become a drug dealer, sell things that are addicting, etc. He doesn't run a tobacco company.
