> I feel uncomfortable interacting with people of lower social classes. I don't care what they think about me. I just feel bad that they might lack respect or comfort in their work, or that their general life position may be unpleasant.

Just so you know, starting at say $80K for family income there's no difference in happiness between the lowest and highest ends of the income scale. Do you think Will Smith is happier than you?

Also watch any of Mike Rowe's shows, namely "Dirty Jobs", and tell me that these people are less happy with their jobs than you.
