That's just it, they typically aren't rich. They are standard middle class millenials that should be playing smart with their money, but it's just burning a hole in their pocket.
As far as apartments near shopping malls that is, I'm not 100% sure the demographics of someone renting near a stadium, but I would suspect it would be the same. The rich aren't stupid with their money generally, that's why they are rich. It's our retarded middle class that never wants to advance in life.
I mean just relating this back to concerts and tickets... I took one look at the prices of guns n roses reunion tour and laughed at the thought of paying $200-500 each ticket for a couple hours of shitty seats and some good music and overpriced crap food and beer. I Would rather worry about having a nicer house that I live in every day.
