i think what the 80s post 16 work scenario looked like rather depended on where you lived. Mid to late 80s, and into early 90s, there were huge rates of unemployment generally in vaste swathes of the North. (Remember Boys from the Black Stuff, Auf Wiedersehen, Pet, Brookside?)
There was a massive issue with youth unemployment as the apprentice system had largely disappeared, replaced by some frankly exploitative and useless youth training schemes, and there was the same issue with getting an entry level job with no experience. Again, maybe the North South divide as it was termed but certainly in my area of the North there were no options I know of where you could walk into a job and learn in a few months, and if there were low skilled jobs, the employer would still be looking for work experience related or not to demonstrate general work competence, reliability etc so young people would be bottom of the list.
maybe it was different down south. I know some people tried to move but even then the discrepancy in house prices, rent and cost of living was there. Again, in media, there was a whole off shoot of Brookside that focused on that.
When I applied for Uni, I applied no where down south except Oxbridge, and then only there as the accommodation was provided for 3 years. There was a very negative mindset in my school;’why study? It gets you no-where, there are no jobs.’ At one end there were youth training schemes that went nowhere, at the other there were graduates unemployed after their degree. I can really empathise with young people today in this scenario, it’s even worse at the 21 plus degree end saddled with debt.
