There won't be another one along in a few minutes because of the unique combination of his incredible pathological narcissism, off-the-scale amorality, and immense wealth. His intelligence doesn't figure into that picture.
I've said it a few times: I'm in real estate finance. I knew this guy was the absolute worst of the worst in 1989 when I was just starting my career due to first-hand experience. He was a bully, and a fucking dumb as shit bully, because the arguments for why he deserved a loan were inane, his threats if we said no ludicrous (and would have been ineffectual if he'd tried to make good on them), his track record as a businessman already in tatters, and his refusal to provide his tax returns for a loan on which we demanded -- for starters -- a personal guarantee patently ridiculous.
But he found money -- plenty of it -- from others. In fact that's been true his whole life. So I would say his determination to find people dumb enough to trust him is a hallmark of his. Is that persistence, or intelligence?
