A certain class of people want their kids to be the 'best'. Meaning Oxbridge/Ivy League, specific professions.
I agree that it's unnecessary.
There's no need for all of that in the UK.
You only need grades good enough for what you want to do. Passing exams mean nothing, it's all about choosing the right educational path.
If your child isn't naturally academic then pushing them to get A*'s isn't going to work. And exams aren't an indicator of intelligence.
Autistic DP is excellent at his profession, acknowledged by all his workmates, but never got anything higher than a C at A-levels. Scraped into a v.low ranked uni by the skin of teeth, now earning £££. A tiger parent would have considered him a failure!
At the same time teenagers/young adults need to know the value of money. And how their chosen path fits their personality.
There are a lot of career changers in my line of work, so I have a unique perspective. Many of them got a shock going into the working world. They got a degree in 'what they loved', had a great youth, blah2 but never realized just how much money mattered. Trying to get their first house in their 30's, saddled with children, and trying to change careers is hard work.

Also a lot of complaints that the degree apprentice wage isn't enough to support a family, which I found ??? Apprentices cost us in terms of training time, not to mention the degree we pay for. It's not our fault that they chose to do this alongside having other responsibilities, but there's a lot of entitlement.
The majority of people don't have a 'great passion'. Even if they have a degree they chose something they're vaguely interested in. They come out not knowing what they want to do, eventually fall into a job. And then just go from there.
You don't have to do a job you hate, for money. But equally, you don't HAVE to do something you're wildly passionate about. It just needs to fit what you want. As lifelong learning, you can always change careers, but it's a lot easier having £££ behind you.
