>My previous employer called this victim mentality.

I do too. I think the world has made a lit of victims and keeps reminding them who and how they are being victimized, even if it isn't the case. 

>Also, as an amateur photographer, it drives me crazy when people complaining about paying a hundred dollars for an "hours worth of work" or a 1-hour photography session.

It would be different if they ad to sell their skill that took years of practice to acquire.
