The fix may take a long time, but the bigger problem is there are no workable ideas for a fix. It's not like better education hasn't been thought of, attempted, and tons of money dumped into it. Results have been mixed at best.
Did I give the impression that better education is sufficient to solve the problem?
* The British system may not be superior, I left uni in 2006 and the UK in 2018, and UK politicians have been fiddling with education seemingly forever.
But that just means you should substitute whichever country is doing education best at the moment; the point is, even obviously correct things are still hard in the world of politics.
