In an admission as to how parlous the finances of the UK are, especially wrt funding pensions, Lord Bichard a former benefits chief has suggested that retired people should be encouraged to do community work such as caring for the "very old" or face losing some of their pension.
He is right to prompt a discussion about how pensions can be funded. However, I am not so sure that this is a viable solution.
Aside from the obvious political difficulties of "selling" it to the public, a good many fit retired people play an active role in their local communities already. As such, it is unlikely that even if this idea ever came to fruition it would achieve any measurable financial benefits.
