You know all those rich bankers that we all hate?
One of the reasons that they are rich is because they're in charge of our pension funds.
I have an (almost insignificantly) small pension from back in the day when I used to work for a large industrial company.
My wife is a teacher and so has a (still) reasonable pension provision, though money she "invested" in a private scheme became practically worthless during recent financial troubles.
The only shares I've ever owned (in Bradford and Bingley) went from being worth about £2000 to worthless over a few years.
I can't see myself ever putting any of my money into the hands of fund managers (via a pension or otherwise) because they don't seem to produce results any better than random investment.
My personal strategy is to put any spare money I have into paying down the mortgage.
Once that is clear I'll start worrying about what to do next.
