There's this theory that illegitimate or fast gains lead people to not value the gains as much, thus more frivolous purchases.

That's interesting. I suppose that if I won the lotto I would want to try expensive things to see if they were worth the extra money. I've never dried off with $700 towels before, would I feel $695 fancier for using them?

I think the $700 of fast gains won't feel like $700, so you probably wouldn't experience the full utility of whatever fancy thing you buy.
