The top 5 guys on that list are going to be whoever is head of the 5 NY crime families at any given time. Individually, they may not be as wealthy or have the clout compared to another mafioso. But as boss or acting boss, their power extends to the entire family. So, by virtue of that, that will put them at positions #1-5.
I would agree with that to an extent. But the bonanno family doesn't have a boss at the moment. And what about a genovese capo who earns more money than the boss of a smaller family? Sure he's the boss, but isn't it possible that a capo from a larger family could hold more weight?
