If you look back the series from the earliest episodes, anger was a central theme of the entire show. The Sopranos, though set in a mob context, was often a commentary on society in general. And, obviously, there's a lot of anger, dysfunction, violence in our society today. I've never met a mobster but I'd be willing to bet a guy like Richie Aprile is much closer to the real thing than Don Corleone.
