After Vito returned from the hospital to comfort the dying Genco, Puzo writes, "...he informed Hagen that he was now officially the new consigliere to the Family. This meant that Hagen was sure to become a very rich man, to say nothing of power."

This raises a question:

Mafia's all about power and money. We see plenty of power being exercised by Vito, Michael and Tom (on occasion). But I don't recall reading (or seeing in the films) any evidence that Tom was "very rich." If anything, he seemed like a 24x7 family retainer. I inferred that he lived at the Mall, and certainly his and his family's needs were taken care of. But "very rich"? For that matter, while I don't doubt that Vito had great wealth, I don't think money motivated him. His primary motivation seemed to be about achieving security and independence for himself and his family by acquiring a strong base of power and influence.
