But these are people who grew up doing the "responsible" thing and listening to the advice of teachers and parents. They made good grades whether or not they learned, did extracurricular activities whether or not they enjoyed them, and otherwise put aside any sort of personal decision-making for 21 years, in the idea that a college degree would get them "success."
Given that, it isn't enough to just say "get a job, bum." They need some new, concrete picture of how life works. With ideas like, do things you enjoy and practice hard to get better at them, not to impress other people. Or, work hard even at things you don't like, if it gets you the money, time, or skills you need to do something else later.
And then the question is, how would you arrange a family or a school that produces people who have these ideas naturally? Probably there'd be a lot more opportunities for kids to do meaningful work/play, apprentice learning a trade, and less focusing on getting into a prestigious school.
