Interesting then that few of the people we encounter there are rich. I'm sure Alex got hers for free or otherwise on account of being a Bardot, and MC and Nancy lucked into theirs free or almost-free, but Penny, Dalia, Annie, and Luna all presumably bought theirs at the regular market price (as well as Gertrude's husband buying two, and he has to be pissed at Gertrude and/or Nancy). None of them appear to be "rich;" they're all squarely middle-class, or perhaps upper-middle-class.
And even in 2025 dollars, $3500 certainly isn't cheap, but it's in reach for a middle-class adult who decides that's what he (or she) wants to spend it on. A teen or pre-teen? Maybe not so much.
