I'm not understanding this question, You don't need money for a racket? Someone please explain..
Members of the Family had the opportunity to borrow money from the Family if they needed it when going into business. Sometimes they needed money for a small investment perhaps in a fully legit enterprise. Sometimes money was needed to start a loansharking operation (for example) and so on.
If you remember when reading Pistone, the part when Brasco and Lefty wanted to start loansharking activities down in Florida, Sonny Black explained to them that the Family consigliere, Stevie Cannone sat on the Family´s money and was going to lend out money to them.
