One wonders how much wealthier Bezos would be if he had the same procedures done.
Secondly, I think Elon's role is a lot more outward-facing than Bezos's role, and that would probably have been the case even if Bezos was more attractive, so I doubt the procedures would have had as much an effect on Bezos's success as they may have on Musk's.
But he would be hated a lot less, IMO.
