You can charge older people more for goods and services than young people because the former have more money than the latter.
So holds the Court of Appeal.
I'm sure that the fancy-schmancy "luxury health" fitness club in the Bay Area here decided to charge 18 to 29 year-olds a (much) lower monthly fee than its older patrons because they were concerned that single people in their 20s in the Bay Area had much lower disposable income than their regular clientele. Definitely.
It's not that the fancy club wanted to encourage the young and fit to populate its club as opposed to the old and pot-bellied. No. Definitely not that. Had nothing to do with that.
It's just that 20-somethings that frequent luxury fitness clubs in San Francisco have much less money to spend on such things than 30- to 40-year olds with families.
Yep. That's why.
