The social and economic structure has changed, and ordinary people have fewer opportunities to see the mafia.
The economic structure was relatively scattered in the past, so when I was young, the mafia made money by relying on some illegal places (pornography and gambling) or by violently monopolizing some entertainment formats: Internet cafes, game halls, billiard rooms, skating... These places naturally interact more with residents' lives, so residents feel it clearly.
Now drug gambling has been severely cracked down, and the porn industry has already adopted a split model of compliance and avoidance of law, and does not need violent protection (compliant operations can be directly protected by the white road). As for the traditional violent monopoly of entertainment formats, compared with the earthwork, sand and stone, building demolition waste, the income is not attractive. So today you see that the cases of mafia bosses sentenced in various places basically do not involve the lives of ordinary people.
To tell a joke, New York residents actually don't see the mafia now. This is not because the mafia has changed its mind, but because now they have a better way to make money and don't collect protection fees from businesses.
This is essentially similar to the fact that many corrupt officials who are caught now do not directly accept money or directly embezzle. The economic structure is improving.
