It's not about technology or fashion. At 22, we had real responsibilities, for running local/small businesses, with the freedom to hire (and fire) people. We were trusted to make sensible business decisons and by and large, we did okay.
Most young people I knew in the 70s and early 80s were not running businesses, some young people are today. You are extrapolating.
A friend of DS is stressing, big time, about going to university. WIth a string of A A levels, and unconditional offers with scholarships at RG unis. Yet, the person is terrified of making any decision. I don't really understand why and I suppose that's why I'm asking these questions.*
She seems very wise. As a university lecturer there is nothing that worries me more than young people taking on a huge debt for an education their parents want for them, then finding they are not coping (A* at A-level is really no guarantee you will do well at uni) but feeling obliged to struggle on until their health breaks down. It's not only about the damage done to them; it's about the complete uselessness of the experience. They are not learning. Waiting, choosing carefully, not taking this usually one-in-a-lifetime experience until you are mature enough to make the most of it would be so much better and so much more productive.
Universitites are far more pressurised enviroments than they used to be: there is less room for failure, less room to just bum about, which is what a lot of my generation seemed to do.
As long as your friend's dd takes a job and contributes to housekeeping costs, she is not staying a child, is she?
My concern is that if this person doesn't take a place at university, the career prospects locally are bleak
No bleaker than if she has to leave uni because she can't cope. In fact, compared to that scenario probably less so because she could have spent the intervening time getting experience in the workplace and getting glowing references.
So may older people seem to think it's simply a case of getting to uni and all will be well. Students do fail, you know. We don't guarantee success.
