Ah, well, you see, you know when they said "we're all in this together", and when they said that unfortunately public sector workers wouldn't have to worry about a pension. because of hard times n' all that? Well, er, you see, um, the "all" isn't actually "all", there was some small print. You may have missed it.
The small print said that, er, um, some people, like shareholders in privatised utilities, like private pension funds , well they're not "in it" with us. No they're different. screw them, and so if the price of bills was frozen for a bit, they'd have to forgo a bit of pension , and that wouldn't be too bad.
Note: Obviously when I say small print, I don't actually mean it was written down. It's just an understanding between a party and its friends and donors. No the print part refers to getting tame papers to slag off Labour and raise scare stories for daring to talk of lumping them in with those dreadful smelly poor people.
Fixed that for you
