Difronzo isn't the boss of anything. No one in Cicero/Chinatown considers Johnny DiFronzo to be the boss of anything outside of the legitimate businesses his family owns. His guys can't even be considered Outfit gangsters anymore. Running legit businesses doesn't constitute Outfit activity, regardless of whether or not you think it's "smarter". The Cicero crime family is just that: A CRIME FAMILY. They aren't interested in becoming white collar types because they're....ya know....GANGSTERS.

Someone like DiFronzo wouldn't have even been in the running for boss 50 years ago.
