Well, the whole point of the Mafia is that it's a sort of reactionary movement to defeudalisation/uniformisation in places that are far away from where the power centralizes (the exact same reason why Yakuza started after the unification and why a lot of gangsters are from Kyushu).
It also pisses me off that people use the word mafia inappropriately, for example "Russian Mafia" or "Moroccan Mafia" have no meaning, these are not feudal organization like Mafia or Yakuza
