Marginal reality of risk.
Big shot CEO’s bad outcome if they get fired for doing a terrible job is they are still rich. Assuming they’re not outright criminals, and also happen to get caught and punished for that, anyway.
Is Musk doomed to get whatever normal 9-5 job he can land if things go so horribly with his investments and endeavors that he loses everything? No. No matter what, he’ll never again work a real job if he doesn’t want to. His fame/infamy is bankable enough he’ll never need a real job to make decent money. He’ll live well and his kids will go to fancy prep schools and all that. His worst likely case (short of, like, going to prison—talking pure risk to his finances) is better than the best likely outcome for nearly everyone else in the world.
The marginal reality of risk, above a certain level, approaches zero. The numbers are big, but the risk is a fantasy. The average poor immigrant is taking more real risk than any of these people do, sometimes in their whole lives, every day. Even the average pampered software developer does.
