I see it more that adult life is delayed, since there's the opportunity and privilege to delay it. It's kinda rich kids acting like their poor kids, 'cause that's kind of a cool thing to do.
Not everyone of course, but those $100,000 tricked out vans don't pay for themselves. Lots of career folk do roll those out on weekends, but some of those are owned by twenty-somethings. In the minority, you see some people scraping by.
