Young people don't want to work hard because there's little incentive. No matter how hard you work, unless you're in the top 5%, you're far priced out of most places most people want to live. You can afford everything comfortably beside housing & health care (which you don't need much of when you're young) on a relatively low wage in the US. So you've pretty much given up on housing. What's the point in working hard?
That, and what's the long term strategy? Do they turn 30 and flip from working part time at Pizza Hut to a professional salaried career? Good luck getting an interview with that CV.
I'm not saying it's an ideal situation to be faced with, but tuning out is just going to make it worse.
