Your guess is as good as mine. However, I believe capos have millions on the street; for some, the yearly interest might run into 7 figures. For example, in Philip Carlo's biography of Gaspipe, when some of the Lucchese capos were whacked or disappeared into witness protection, Casso or Vic Amuso took over their shy business. And some had multimillions on the street. With that much money on the street, I'm anticipating weekly beatings.

On a side note, loan sharking was involved in the violent Billy Batts scene in Goodfellas. Supposedly, Billy Batts had a nice shylock business that he left behind when he went to jail. Jimmy the Gent took it over. When Batts came out, he wanted it back. So, Jimmy would have to give it up or have Batts whacked. I believe that's why the movie had Jimmy directly involved in the the murder.

Here's an interesting tidbit about Tommy DiSimone's murder: Jimmy was protected because he was such a solid earner. However, Tommy tried to rape Karen Hill, and Paulie Vario sacrificed him to keep the peace.
