Well I mean it's all relative...
I don't want to get into a place where everyone and anyone who goes to lots of shows and tends to quite often be very close falls into the "crazy, entitled psycho I think I'm better than you and deserve this" category... and while I'll certainly judge someone based on observed behavior, I won't assume to know what their financial background is.
I know someone who had no family to care for who made some financial sacrifices in order to travel the world following the band on Vertigo... Europe, Australia and New Zealand... to fulfill a dream. This person is a good friend and I don't consider him to be a crazy person whatsoever (although to be fair, we're all a little crazy to the outside world when it comes to this band).
I have another friend who's been to almost every show so far this tour. His profession and financial well being allows him to do it, so he does.
And then there's a third, former acquaintance who would go to show after show after show, yet was nearing 30 and still living at home working retail. And of course I've also had my fair share of run ins with the stalker types, and the entitled, and those who think they are somehow better than everyone else.
The bad seeds out there, or the misguided, tend to get all of the attention; and deservedly so... But there are many more "uber fans" who don't fall into the stalker, entitled douchebag category; yet unfortunately get lumped in with them sometimes.
