This is a massive challenge to solve; we’re in the early stages of the fourth industrial revolution.Sorry to focus on one part of your post.
The issue is that for over a generation now all kids have been told they need to go on to University, more education. There are a significant part of pupils that neither have the desire nor aptitude to do so, but do have the aptitude to be brickies, chippies etc. etc. but in a school (not college) environment this is not fostered or even given a look at as the schools are only interested in churning out University clones.
if you don't make the grade you are considered worthless and are basically dumped out of the system, no guidance or other options are given to you. This should be picked up earlier by schools to prepare these kids for other avenues and to be shown that 5 years studying Media as opposed to an apprenticeship where you earn money while getting a trade is just as worthwhile.
A lot of traditional trade jobs are going to disappear as automation becomes the norm. There are already robot bricklayers in the UK and robots that decorate. Manufacturing even a very small scale is near automated. Within my lifetime, I expect to see driving jobs disappear. Retail is only go ever more more online and more automated.
Much of this provides opportunities, but it’s got the potential to leave a lot of people behind too. I think there needs to be a very serious debate about what we want from education.
