Joe Bonanno WAS a very greedy guy. This fact I know personally. He was greedy in the sense that he kept his men down. Even his best and closest skippers. Boyhood friends. He made them skippers, but largely kept them "barefoot and pregnant" all their lives as the saying goes.

Unless they themselves were sharp and earned separately, he gave them zero!

That said. The "Castellammarese Clan" was probably the most secretive and blood bonded of all the five borgatas. Starting with Maranzano they were an extremely close-knit, "closed" group in many ways. Especially those Sicilians from Trapani region. The other four groups were often kept in the dark and at arms length. The Castellammarese generally dealt amongst themselves for decades.
