We have under-sized highly technically trained armed services, facing an increasing number of threats from hostile countries. They do not have the time or resources to wet nurse a bundle of school leavers who think it might be fun to play being soldiers for a year.
We have a territorial army of reservists, why not encourage these youngsters to join the territorial army instead.
It is nice to talk about a years voluntary service, but there are well in excess of 350,000 school leavers every year. Exactly how would you fid jobs appropriate to each child, plus full criminal checks.
Then what work would they do? Probably work now done by lower paid carers, manual workers and other people in marginal jobs. This will mean higher unemployment among this country's most marginal and poorly paid workers.
Sounds like a Green Party policy.
As for Anything has to be better than paying unemployed young people to stay at home in bed staring at their screens and phones. The solution is to make benefits for 16-21 year olds dependent on attendance at educational and vocational classes specifically designed for this particular group of youngsters.
The problem is that many of this lost group of school leavers and school truants, is that many are not claiming benefits, but, as many of them still live at home, they get by with doing odd jobs for cash or working on the black.
