The death of the social clubs was purposeful...in particular, Joey Massino ordered all the Bonanno social clubs closed due to the ease of surveillance for the FBI. But more to your point, the death of the all Italian neighborhoods has been a real blow to the mob. The local capo and his crew could always count on the insulation a friendly (or fearful) population...now that has disappeared to a great extent, especially in the smaller cities....all the little Italys are either gone or just a single street of restaurants anymore. On the other hand, it has forced the crews to be more cautious and secretive.
