I'd say that student is very astute, because I share his/her perspective entirely. One of the satisfactions of the show *is* that Tony and his crew serve as the audience's proxies in getting even for the many humiliations that people suffer every day in the hands of authority figures. One of my favorite scenes is when Tony and his chief goon go to a fancy country club to put the muscle on some pompous doctor who is too busy to see Tony's elderly uncle. Tony very smoothly humiliates the doctor and intimidates him to the point that the doctor falls back backward into a water hazard. The next day -- mirabile dictu -- Tony's uncle gets a call saying the doctor would just love to see him, the sooner the better. Seeing society's powerful get bounced around and humbled occasionally is one of the joys of the show. But there is much more to The Sopranos than that.
