There is a very good reason for this: to make such an agent of change requires intensity beyond what most humans can endure. I don't think Bezos or Musk or Jobs have/had much of a life outside of work. I think it's also clear they all are/were obsessed with their companies. Obsession and hard work, sustained over a long period of time. People capable of that are few and far between. Add in the luck factor, and it's a miniscule number of people.
