I always thought it was the Tories who started the move to putting more people on sickness benefits, particularly when the mines were shut down. In that way, they were kept off the unemployment figures.
The government haven't raised wages though. Public sector salaries have been largely frozen and have fallen in real terms. All they can do is encourage the private sector to raise wages and the best way to do that is to stimulate growth in the economy, create demand, increase output and therefore increase demand for labour. But, as I've said before a few times, that has to be part of a complementary cycle involving demand and productivity. The problem is that productivity hasn't increased and wage growth is noticeably slowing. I argue that cuts slow down growth because it's a well-proven part of economic theory that cuts in private expenditure have a proportionate impact on public expenditure (the multiplier effect) although the actual numerical impact is open to debate.
I've never argued against the need for governments to ensure expenditure is within acceptable limits and that public spending and overall net debt is proportionate to our economic growth. But sometimes you have to increase that spending to take up slack in the private sector. That's economic orthodoxy until the private sector picks up the reins again, the economy starts growing, tax revenues increase and the gap between revenue and expenditure falls (and ultimately is eliminated). As an example, my current mortgage is ten times what my first ever mortgage was and that sort of debt would have been unthinkable all those years ago. But it's about the same ratio to my income as it was back then and actually represents a lower proportion of the value of my property than it did back then.
