Private sector pensions are one of the great scandals of our age. Only 40 per cent of private sector workers are now in an employer-sponsored pension scheme. It’s even worse with low-paid workers: only 20 per cent of those earning between £100 and £200 a week are in an employer-backed scheme.

But the argument should not be to drag down the pensions of public sector workers: it should be to drag up the pensions of private sector workers. Why punish public sector workers for the bad practices of private sector employers? If we do, we end up in a race to the bottom.
