Yeah, he was definitely rich. And extremely well-connected society people. He said his father had a nervous breakdown, connected with amphetamine use and his mother sleeping with his dad's assistant. His step-dad was a rocker and recorded with famous musicians. His mother was an actress (basically B list).
How rich, then? Well, in the 1% of Americans, in money, and the .001% in society.
You can't learn anything from people like him, some boomer who had an infinite sea of millions of opportunities, and just chose one of them.
