In fairness to Broon & Blair, it was Steve Webb who introduced it, as part of the Lib Dem Co-Go. At the time, Webb said the changes should not be foisted on the private sector, and he has been vocal this past twenty four hours about it. I don't think he's scaremongering when he says it's the thin end of the wedge, but there again, the proposed EU harmonisation of inflation indexing is also just as threatening.
I also think it makes further tinkering with public sector pension schemes more likely.
