Thatcher did this in the 80s, 6/12 month schemes, paid for by the govt, these often led to employers using kids to do menial tasks before getting rid and a new face.
The Youth Training Scheme (YTS) was an on-the-job training course for school leavers aged 16 and 17, managed by the Manpower Services Commission. The Scheme was brought into operation in 1983 by the Conservative Government to replace the Youth Opportunities Programme
Employers are simply not going to invest in an employee on short term political schemes (that can change on a whim i.e by the next GE in less than 12 months time) and where the trained person can go elsewhere for far more money.
He and the Tories have had 14 years to unleash a tidal wave of opportunity..... the guy is an idiot, even Thatcher got on with her version within 4 years.
