There's far too much emphasis on degrees and has been for too any decades. Why this nation values a degree from a former poly (and I don't mean practical/vocational degrees in pharmacy, electrical/mechanical engineering, etc) more highly than technical and/or vocational qualifications I shall never know.
I also don't think it helps to conflate intelligence with academic ability or more imortantly, support.
Step left school at 15. Served an apprenticeship in carpentry and then one in French polishing because he loved wood. He had a specialist building trades firm and lots of contracts with English Heritage, etc. He usually had at least 20 men working for him and dabbled in antiques too both as a restorer and an investor. He will read reference books but not a novel and he doesn't write except notes for a quote. Mother did all his paperwork. I suspect he has undiagnosed and severe dyslexia and would never admit to it. He made a great deal of money.
I dropped out of uni in 1978! No degree obviously. I then did a cookery course, secretarial course, spent some time in Europe. When I returned I got a junior job on a syndicate desk and was selling Eurobonds within three years. By the time I was 30 I had a house in London and a small mortgage. It funded seven years off with the children after I was married. When I went back to work I got some professional qualifications, exceptionally because I had no degree, and then did a Masters.
The UK very sadly places far too little importance on the vocational trades which often extrapolate to people running small businesses and becoming employers. We should value those people and trades far more highly and accept the fact that many of those involved in them earn far more than nurses, teachers and policemen, etc. Where they don't do as well is in the context of paid holiday, paid sick pay, 100% paid mat leave and pensions. It's vital they have critical I'll health insurance.
Where would we be without:
Hairdressers
Mechanics
Plumbers
Electricians
Builders
Carpenters
Dry cleaners, etc
We need to value all those trades far more highly and that value needs to start in early years' education. I have met far too many teachers, including MIL, who are a bit sneery about them.
