It depends on the person. An asshole former friend of mine inherited some money and started talking about all the stuff he had bought, but would still bum cigarettes and ask other people to buy him beer saying he never had money on hand or had forgotten his wallet. Then over beers he would talk about his new wall-sized tv or girlfriends diamon necklace. I got bitter, but more because he was a dick about it.
I don't generally mind when people are better off than I am, because I have enough to get through my daily life and that's what matters to me. But money isn't all there is in the world.
A different friend of mine is a proper gentleman and when I met him years ago, I greatly admired him. I've learned from him and never resented him for being awesome, because he's also a really nice guy.
TL;DR: It really does depend on the person and how they're 'better' than me.
