Whatever. There's a big difference between feeling inadequate while sitting in your third vacation home and working 40-60 hours a week at a job you hate because if you were doing what you actually wanted to do instead you'd be starving in a ditch somewhere by now.

Probably the best predictor of if you're going to be upset about people having more than you if you've got $10M is if you're upset about people having more than you when you have $100k.

There will always be people who have cooler stuff than you. If you get upset about it when the cool stuff isn't like stable housing, food security, and decent transportation, the problem isn't lack of funds, it's your attitude.
