The demographic timebomb and its impact on our ageing society was under discussion at a Fabian conference this morning.
A packed room tuned in to hear Vince Cable, economic whizz and everyone's favourite LibDem, turn his attention to pensions, and the potential conflict between the needs of the young and the needs of the older generation.
With increasing numbers of us living longer and expecting a good quality of life, the pressures are on the state to help at both ends of the timeline, he told the Fabian/Housing 21/Counsel and Care Ageing Society Policy Confererence.
As Cable suggests, in a recession those most hard hit may be the teenagers who cannot get into the job market and are stuck with ever increasing debt.
Discussion among the major political parties about protecting the health service last week, suggested a value judgement putting the needs of the elderly - the biggest users of health care -- above the young, he suggested. This didn't feel like the most populist thing to say when the demographics of the audience was definitely swinging towards the former.
But Vince plugged on - obviously unworried about a popularity poll - to talk about another timebomb - public sector pensions, a subject he dubbed "the biggest debate of next year".
Pensions don't feel like the most popular of subjects generally right now; what with M&S deciding to pull the plug on its scheme last week, and columnists (and others) suggesting public sector pensions are/should be due for the chop.
The problem is private sector schemes feel unreliable and often have costly fees, particularly for small savers, and with public sector pensions looking to have a gloomy future, the motivation to put money away at all seems to be draining away.
As those baby boomers head for a shifting retirement package, not enough is being done to build confidence in any alternative savings plan which feels like a safe or productive place to help people plan for their old age.
