It is actually a minor theme in The Sopranos about the role of the Italian Mafia today.
Basically, the Mafia grew up in poor immigrant communities where the immigrants suffered some mild racism. Over time, the immigrants became integrated into American society. There are some stereotypical Italian-American industries like hospitality and construction, but it isn’t out of place to see successful and educated Italian-Americans in all fields.
After the RICO trials gutted the Mafia, what was left didn’t have power they used to have and a lot of the smarter Italian-Americans could go into legal careers. This has caused a really bad brain drain for the Mafia, making it less effective and powerful.
There is still a Mafia around, but it is a shadow of its former self.
