You're all missing the point.
UK public sector pension went through a slight reform three years ago to provide sustainability for the next 50 years. Public sector pensions as a % of GDP is set to FALL continually over this period. The figures were compiled by Lord Hutton who commissioned the fucking report on behalf of the Government in the first place. Money isn't the issue.
The public sector pension reform from this Government, whilst predictable, is nothing more than reneging on contracts due to ideological beliefs. If you still wish public sector workers to receive less, fine, but you're in support of a race to the bottom and have no concept of facts. Let me guess, Thatcher, despite killing off our manufacturing base and leading us to the financial problems were currently in, was a brilliant PM?
Oh, I guess there is one scenario whereby public sector pensions would become unaffordable - the Government destroying what was left of a brittle economy, hmm. Well, at least the banks will be able to buy up a shed load of cheap stocks.
