"I could never see myself wearing an $80 pair of jeans" sounds like a judgment to me, esp. when $80 is still far more than you need to spend on a decent pair.
In futami's defense, I bought a nice ($120) designer messenger bag (Porter) when I was living in Tokyo and was given grief by my gamer friends over it. When I pointed out that the cost was less than two games they'd bought over the past month and played for fewer than 30 minutes each, they insisted that that was somehow different. I used (and continued to use) that bag each and every day and <3 it to pieces. So I'm not opposed to spending money on nice, non-gaming things.
That said, $500 is still a lot for jeans. Clothing is a continuum, and there's a lot of room between Target jeans and 7 For All Mankind. You're throwing the bell curve just as much as the cheapo-gamers you so despise. The sooner you accept that the sooner we can all move on.
