IME, some university-educated parents push their kids to do so because they think it's the right thing to do regardless of their child's ability.
There are some schools push for the university route to make themselves look better - even with guidelines in place that all post-16 and post-18 education and training options should be shared without bias, there is still an opinion - as shown on this thread - that apprenticeships are for 'the kids who need' / the kids who aren't academic. There is also, even in councils promoting other options, language used around certain training that treats it as turning around a bad situation rather than something to aspire to do which discourages some.
I also think we have an issue where in some sectors where we're seeing those places that use apprentices a lot of cheaper labour, but don't keep them on and the places who don't want to do any training at all who aren't hiring young people. Plenty of young people who do go the apprenticeship route, while not getting into debt (unless they leave early, then they can occur some fees), do end up going through the same issue their university peers are of struggling to find permanent employment. I know plenty of both who are in the agency cycle.
I do quite a few young people who aren't going to university, at least not right away, and my kids know even more. My DD2 is in Y13 at a college and in her course, more people are planning on going onto another college course after they finish this one to build up a broader range of qualifications and work experience rather than go to university.
But the completion rate for a Level 6 apprenticeship (undergrad equivalent) is 65%. Equivalent uni completion rate is 85% I think, though lots of variation within that.
That matches what I've been seeing. While some of it is often a higher workload, I think part of the issue on the higher and degree apprenticeship side, IME, is the go-betweens, the training providers that employers are going through to handle the paperwork and most of the communication side, and it's another point of failure.
I know more than one young person who didn't complete their degree apprenticeship or cadetship because errors from the training providers that weren't communicated until the education provider or employer found out and told the student - some the error meant they couldn't complete in the timeline and were given no support on how to resolve, just 'we can do those bits you missed later'. Much like people complain about universities, some apprenticeship training providers take the money and do nothing.
The Luddites failed. The industrial revolution moderated by social evolution has been an amazing success in improving living conditions in the industrialized countries.
The Luddites protested against the lowering of wages, unsafe working practices including an increase in child labour, erosion of workers rights and autonomy, and reduced quality of products, along with being replaced in the workforce.
Many didn't experience improved living conditions, especially not those forced off the land and into the factories. Many of those improvement came from the social evolution of protesting against the very same things the Luddites did, some far more violently than the Luddites did. Industrialisation on its own didn't do that. The Luddites may have failed, but that doesn't mean they were entirely wrong.
