^Those are good points.
An advantage of rethinking education and seeing 16 as a start for vocation training while still home is that there could be more room for "false starts". Any scholarships or grants-in-aid could go towards the final choice.
We get the sort of society we subsidize. Non-vital fathers, Over-worked and isolated mothers, kids who blow tens of thousands on sheer time-wasting nonsense...
I'd rather see kids still at home until 21 instead of back in the basement at 28. They progress to 12 or 13 and then slide down until 21 anyway.
