I mean Carlo Gambino was born into mafia royalty so to speak. Likely had a lot of relatives on both sides supporting his moves to become boss. Joe Bonanno same thing.
Sarfo Jr made a lot of dough with the Lukes, no sure how much of a powerhouse he was though. Still stuck to the code.
Allie Boy Persico.
Thank you for mentioning Carlo. I would say Tommy was the real deal as he was extremely successful. Maybe not like his father exactly but still more than most of his peers.
