It also usually has no decent mass transit, which means more personal vehicles (and without a job, that means the vehicle is likely to be an older internal combustion one).
They’re still operating on the old assumptions of what makes for a good American middle-class suburban life, drilled into them by parents who grew up in the 1950s and 1960s. Heck, I’m well past my 30s and I don’t live like that (as much for my own physical and mental well-being as for doing my part to save the planet).
I do notice a lot of young people (under age 25) rejecting a lot of those values. For example, most of the teenagers I know aren’t interested in owning a car. Admittedly, these are kids in prosperous urban areas where quality mass-transit exists or is being brought on-line, and many of them are off-loading driving to less privileged gig-economy workers. However, it’s a definite change in mindset from when I was their age.
