I would certainly argue against that. The public sector includes the Health Service, Fire, Police, Defence and Social Services. The wealth-creating part is tiny as a proportion of government expenditure. Nationalised industries don't create wealth because they don't have to - they know that they cannot go bust. Every country in the world produces world-class engineers and scientists. In Britain it is often despite the comprehensive education system. Just a look at the government's own figures for the sources of the money it spends will show how little is generated by its own operations.
