I'll tell you as someone around that income range in New York... I don't get invited to parties where we discuss how to screw over the working man. I ride my bike to work, spend half the day there, ride my bike around Brooklyn, watch some TV on a 720p LCD that I bought 6 or 7 years ago, and then go to bed in my bedroom that's too small to actually contain a bed. (The mattress fits.)
Admittedly, I've accumulated some savings this way, but still, New York is really fucking expensive, and it's not hard to spend make what sounds like a lot of money on ordinary things like food and shelter in non-premium neighborhoods.
