But an interesting attempt to give a sense of scale:
AXA also calculated that a woman in her mid-20s working in the private sector would have to contribute almost a quarter of her annual salary every year to get a pension comparable with a public counterpart.
Given that pensions are simply delayed compnesation that means that public sector wages are, by this measure alone, 25% higher than private sector.
OK, to be more precise, 25% minus whatever pension contribution that public sector workers have to make themselves. Different schemes have different amounts but for some reason 6% sticks in the mind. So 19% then.
