It's simple one group tries to feel superior to others by showing off, while the other group does it by laughing at those showing off, because they're not better than everybody else neither socially/intellectually/financially while trying to imply they are.
Not saying one is better than the other, just seems easier and less embarrassing to be part of the second, obviously neither being ideal.
That being said "BrainDamaged" was right about one thing, 16 years later things have not changed that much, before they had sand in they're vag because people laughed at they're riced out cars, now it's because of they're "riced out" life. In both cases as long as it makes them happy I'm happy, but don't you dare try to take away from us the right to laugh at you.....
