If a billionaire like Musk or Bezos had all their net worth and power/fame stripped (no one knows who they are) would they be able to regain their wealth with their knowledge and skills?
Likely not. They could become successful, but I'd bet just about anything that if you took any billionaire down to complete zero they could never get back. Especially since most billionaires start out miles ahead of complete zero from wealthy and well connected/powerful families.
