Hmm ... I see your point, but I doubt if huge numbers would opt out thoughm as there is no viable alternative is there? I mean, private pension schemes are in deep trouble.
I say this as a public sector worker, and my pension contributions may rise by another £100 or so a month, and that's on top of the huge amount I pay in already. All that will do, is maintain the terms and conditions I'm already on - so in effect, it makes me worse off.
However, there's no point trying to escape the fact that the country is in a dire economic mess, and yeap, we're all in this together, so its no good complaining when it hits your own pocket.
At the end of the day, public sector pensions for those of us who've been paying in for a good while already are the best deal going. I mean, who else is going to get a nice big lump sum plus half their final salary index linked for life?
It's not nice having to pay more and not see any more for your money, just the same service, but tbh, I would rather contribute more for the sake of getting a good deal at the end of it. Many public sector workers have made their career decisions partly on the basis of the pension, so its in their interests to do what needs doing to maintain it.
