The true cost of public sector pensions

From the BBC:

At the end of an article which contains the usual whining that "the likely scale of job cuts required would 'inevitably have an impact on levels of public service provision' is this:

Meanwhile the CBI has said that businesses are being deterred from bidding for public service contracts by the need to match what it says are "costly" pensions when staff transfer to private firms. The business group said firms had to pay between 25% and 50% of salary to fund the pensions of ex-public sector staff.

Taking the mid-cost as 37% and assuming that the average (rather than median) salary for eight million taxpayer-funded jobs as £30,000 a year, suggests that the true cost of public sector pension promises is as much as £90 billion per annum, nearly as much as the entire cost of the (bloated) NHS and considerably more than the entire welfare state (excluding old age pensions).

Just sayin', is all.
