The mob was always spkit in two like the Gambinos under Carlo that had two underbosses: Dellacroce for the blue collar crimes and Castellano for the white collar crimes.
Today only the desperates want to joint the mob and only because have no other possibiliies. Now the big families have something in the docks or unions but nothing compared to the 1980s.
Now onlycthe street guys was inducted and only few if them have the capacità to run a white collar racket.
I dont said that have to fight but the numbers are useful to impress the street gangs.
