Since the 1980s we have had hidden mass unemployment government carefully concealed by the use of higher education, 'the sick' and other benefits plus temp jobs.
Employment goes up with recovery sure. But are we cycling around permanent mass unemployment now - and without the money for generous welfare?
And especially because a lot of low-skill jobs and many high-skill jobs can increasingly be mechanised by the use of software. Meter readers, tube drivers and even lawyers and doctors. Vehicle drivers are next.
