I’m about to be really dismissive but a huge part of being wealthy is getting very lucky with timing. You only know who Mark Cuban is because he sold off broadcast.com to Yahoo right before the dot com bubble burst. If he’d held out even a few more months he’d be managing a Wendy’s right now. Once you have a stupid amount of money it is incredibly difficult to not grow that pile of money because wealth compounds. Our society loves the Just World fallacy and if you’re rich that must mean you’re super smart or talented or deserve it in some way. How we’ve seen that’s clearly not the case. Elon Musk is currently imploding Twitter, Kevin O’Leary is Kevin O’Leary, in a lot of cases some terrible people got lucky and want to act like it was all their genius. Truth is they’re as stupid and greedy as anyone else.
