"He's the single most monumentally arrogant SOB I've ever met, and I've spent nearly my entire career working for billionaires where hubris is commonplace. "
You've actually met the guy? Tell us more!!!
Please, do tell
The next time I met him he was exploring a run for mayor, and he stopped by our trading floor to take informal and off the record questions from us as a fact finder. He has some... I don't know what to call it exactly except charisma... but it's clear that the thinks the individual really has no business making decisions when an expert (like him or some other government hack appointed by him, or in the case of his company... hired by him) can make the decision for them. It's just the way he thinks the world should work.
Let the smart people decide, and the rest should just shut up and follow.
