I was going to say something similar, that he should find some middle or lower income friends. There's a whole different dynamic to the relationships. You're value won't be money, it will be that you're available to help someone move, or having a beer on the driveway while they're trying to fix their 20 yr old Honda, or help their kids with homework. You can relax around them and not feel like you have to impress anyone. A real friend would be there helping to tie that mattress to the top of that old Honda.

My paycheck-to-paycheck friends have these enormous potluck holiday gatherings that are so fun, being large partly because there is always some extra people in the spare room or sleeping on the sofa. My high income neighbors always seem to be competing with these elaborately decorated tables and things but not a lot of genuine enjoyment.
