We have several friends in the UK & Scotland. We have talked some of the problem. In the UK kids finish school at 16. Unless they go to college, which gives them another couple years to mature. Putting 16yos in the labor market doesn't work.
For all the progressive socialistic bureaucratic infrastructure they have, the kids get no help.. They end up on the dole or working low level entry jobs.
I also think the kids are taught from grade school that they need not work, because the system will provide, so there is little incentive to excel.
I suspect that all of the EU is similar.
They breed a welfare state...
