I wonder to what degree the hubris causes the wealth. You need a high degree of certainty in yourself and your ideas to succeed in many ventures. I've seen people work their way up organizations who I think are much less competent and thoughtful than I'm, but they at least outwardly present themselves with certainty. Often times people liker that already got promoted away before the downsides of their decisions materialize. In other instances we might never hear about them, because nobody cares about the guy under the freeway bridge who has similar character traits to Elon Musk or Steve Jobs, but got less lucky or was slightly less smart or well connected.
