I grew up in a mining city, too (I read someone else did, as well). So, I grew up with the beliefs that "nothing is free" and "you have to work your finger to the bone to get ahead." And, yes, middle-class people looked down to rich people, "What do THEY know? THEY don't know reality!!!"
However, in my early 20's I became a nanny for a few wealthy families. One family is quite famous, actually, and they have annual "money meetings" in NY with extended family to make sure inheritances are still in tact, what charities to involve the family name in, etc...
I have to say... being rich is fun!!!

I don't see what is so "bad" about it anymore. They love, hurt, cry, and feel just like everyone I know. Some of their friends were annoying and pretentious, but then, some middle-class people I know are quite annoying and pretentious, too!! And for some, let's add bitter.... they are bitter that they don't have what "they" have.
I am also learning not to GASP when they spend thousands and thousands of dollars on something perceived as "frivolous." That is putting a limit on myself. Now, I am looking at things and saying, "Yeah... I would spend $20,000 on that!" Or, "Why not get a room for $15,000/night, how FUN!"
