Gaelicsheep, I didn't take your comments as being aimed at me personally - I did take it (mistakenly, as it turns out) to have been aimed at an amorphous mass of workers who have very little in common. I also loathe the whole "public v private" hype we seem to be exposed to at the moment - I don't like to see either sector being damned, and hadn't realised that you were simply illustrating a point.
Penthesileia - I stand by my comments. The current unaffordability of private pensions is the result mainly of political decisions - regulations which were perfectly reasonable in themselves, and which addressed a specific mischief (companies going insolvent and leaving pension schemes - and therefore employees and former employees - with no pension) have been applied in a way which requires all private pension schemes to ensure that within a fairly short time scale, they are fully funded and able to meet all current liabilities on the basis that they could find a lump sum to an insurance product to secure those liabilities. The difference with public sector pensions is that they are able to take a longer view, and meet those liabilities as they fall due for payment (which, for a 20 year old now joining the pension scheme, will be no sooner than 40 or 45 years in the future, and which are likely to extend 30 or more years after that date) not as a lump sum in advance.
I don't think that final salary pension schemes are unaffordable; they are probably unaffordable in their current incarnation, because most private companies cannot guarantee that they will be around to pay the pensions of employees who will retire 40 years hence - so private pension schemes can't have the leeway that public schemes do.
If there was the political will, it would be possible to establish a pension scheme which gives a known pension for a known level of contribution without (as seems to be the case with splodge's pension) the individual having to take risks with investments. There was such a scheme between 1978 and 1988, run by the government, open to all, providing a known pension.
It cannot be the case in a decent society that people are unable to make arrangements to provide themselves with a pension with a reasonable level of certainty, or are discouraged from doing so because of a complex and costly means-testing system of pensions. Sadly, I don't think that the political will is there, and as to corporate will, they have to operate within their own markets. When most companies provided pension schemes, any company not doing so was at a competitive disadvantage in recruiting and retaining staff. When most companies are closing their pension schemes, there is no particular competitive advantage in providing a pension scheme - you need a critical mass for the market to work.
Anyway, well off track, and I now have to walk the dog unless I want poo on the carpet, which is probably a more pressing issue than the nation's old age pensions.
