Reminder that House started in 2004, 19 years ago.
Im not an expert but I dont really think that the stereotype still holds up, like in a “A pizza restaurant in NY?, definetly a front for the Mafia” or knowing an Italian and immediately thinking they’re mobsters.
The great families in the US had a huge downfall starting at the 70s, and by the 90s they were no longer the big classical Mafia families.
Some of them crashed because of internal struggle, others by the preassure of their greed, and others just went legal.
Also the gov cracked down hard on racketeering and mobster activity.
The Mafia concept has evolved and they moved to other types of illegal activity.
But I think that most people when they think about Italian mobsters, they think about the Godfather, Al Capone, and the golden age of the prohibition and the 50s.
