I'm not sure that legalized sports betting has hurt the mob as much as people say. I remember reading law enforcement saying that people will always gamble with organized crime and many people even prefer it. Same with loansharking, there will always be people who need quick cash loans without the hassle of paperwork or credit checks and possible denials. I attribute the extinction of the Mafia in many cities more to there simply not being anything left. They just died out.
