Most of the megacorp leaders, probably. Perhaps not all, though I can’t come up with a Gen X / Millenial / Gen Z counterexample myself. But plenty of small and medium sized business owners primarily get their wins by grinding for a long time in their respective industry (luck helped get them into that industry but sometimes those industries are really low barrier to entry), and then starting their own firm and delivering consistent excellent results.

Of course there’s also a lot of inherited money who abuse high functioning lieutenants to whip the real work…but if you want to find mostly self made business owners, that’s where you look.
