And, possibly, the youth fetish. When the portrait of the ideal is a 19-year-old guy who dropped out of an elite school, it's not surprising to see the ethics of the over-entitled rich boy everywhere you turn.

I'm not sure that assumption works out. Yes, there are frat boys, but I've also stood in many bus stops and taken many buses in not yet gentrified neighborhoods and highschool drop outs can also be quite aggressive in approaching strangers and chatting them up all the while their target is trying hard to get out of any interaction.
