Mish brings up the subject. I am dating a woman who has a senior in high school. He and his friends just don't care about cars like the prior generations. Nor are they eager to get that first job to earn lots of money. (That is relative. When you've never had a job before and you are 17, $150 per week is a lot of money.)
There are two reasons I think: One is the smartphone. They are now connected to each other 24/7 in ways you and I couldn't imagine when we were kids. The other is the massive influx of immigrant workers over the past 20 years. I am not going to debate the legal vs illegal thing, but go into any fast food joint and you won't see high school kids behind the counter, you'll see middle-aged Hispanic people, primarily women. Why would the manager of a burger joint hire a high school kid with angsty teenaged attitude when they can get an adult who truly needs the work and doesn't complain and doesn't take off if they have a hot date?
