A good education usually leads to a more 'rounded' person, and getting an education is usually an enjoyable experience, as it gives people time to spend on something they enjoy, and to do so in the company of others who are also interested in their subject of choice. Whether it leads to a better paid job is only important if none of that matters to you.
As this is the UK, and there is no escaping the class system, there will always be those who insist that education isn't important, that 'we' need tradespeople, and that 'they' should take up apprenticeships instead of a degree. They wouldn't want that for their own children, of course - just other people's
.
Of course university isn't the only way to succeed. It makes it easier though. There are jobs where a degree is essential, and enough people who insist on one before interviewing people for entry level work to make it difficult for those without. All the same, people who are prepared to work hard can often have good careers with a combination of luck and ability.
What I would suggest, however, is that most of the people without degrees who end up in professional or managerial work (which may or may not be highly paid) will be from families who have contacts, and where the children have learnt to 'speak the language' of their employers at home. For every young person who manages well without a degree there will be several who get stuck with a job, rather than a career.
We don't know how AI is going to impact on the workplace though. It may well be that 'brainwork' will be taken over by computers before long, and that it is manual skills which are valued more highly. For that reason, my advice to a young person (all else being equal) would be to do what they think they will enjoy, close as few doors as possible, and keep an open mind. If they have a subject that inspires them, they should follow it to as high a level as they can - whether it will lead directly into work or not. That applies whether their interest is in Quantum Physics, plastering or the history of ideas.
Oh, and I don't know anyone who thinks that money is equivalent to intelligence.
