I think 'average' kids are falling through a pretty massive crack in the floor of education and life in general.
It's always been the case to a certain extent that the kids who plod along were just left to get on with it. I speak as an 80s average kid. When I left school, after a brief stint in care work, I moved to factory work. The wages then were enough for me to rent a flat on my own without parental help and get a mortgage with my partner at 21. Not that the wages were great, but there was a sweet spot in the 90s when housing prices were relatively stable, cost of living wasn't huge, etc.
Now, the average kids have got no hope. There's fewer factories/manual jobs available, the wages won't get you anything. It's all very well people talking about 'trades' but not being academic doesn't equate to having the aptitude for skilled trades. Added to that, many trades have become more academically demanding than they were.
When my mother left school, she went straight into nursing at 16. When I was in care work, I could have trained to be a state enrolled nurse, which was more practical - based and you didn't need academic qualifications.
Now, to get into nursing college you need A levels or Btec.
There's far less employment 'for the masses' now that actually pays a living wage. It's one reason why kids now end up doing some Mickey mouse degree. What options have they really got? There's no 'reasonable adjustment' for just not being very good at stuff.
Our kids are under pressure to be good academically or have a reason why they aren't. Because, frankly, if you are an average kid, there's not a lot out there for you. Once, you would have been on the factory floor, maybe you would have moved up to supervisor or middle-management. Now it's much harder to start at the bottom and work your way up without much in the way of qualifications. Chances are you'll end up in a zero hours contract position or working 'part-time' for a big supermarket that really wants full time workers, but knows they can get people working 'overtime' whilst only having to give them pro-rata holidays, etc.
There's no respect for the working masses any more. My parents respected the fact that I got off my arse and worked for a living. They weren't disappointed I was on the factory floor. I was a productive member of society, making my own way in the world.
Who wants to do that now, even in the few places those jobs still exist? It barely pays enough to live on without government top-ups, people call you lazy even if you work 12 hours a day doing heavy lifting, everyone wants their kids earning six figures even if they really haven't the brains for it, and the kids who would have once been 'factory fodder' are now dropping into a big hole of doing Mickey mouse degrees to get a minimum wage admin job because at least that's a bit more respected than McDonald's.
