"The biggest income source for any Family is ,and always will be,gambling and loansharking"


The biggest or the most consistent and long lasting? It seems that there have been very profitable, if temporary, rackets in the past like the (already mentioned) gas tax scam, drug wholesaling, and, of course, prohibition era bootlegging.

Also, if Paul Castellano was not killed he would have been convicted in the Commission Case (like the heads of all the other NYC families). I imagine that he would have chosen a more competent successor though.
