We are as a society living longer. We are asked to believe that this makes pensions unaffordable and unsustainable in both the public and private sectors. It is simply untrue. There is a tendency for analysts to suggest that demographics and population dynamics are undeniable, absolute truths. The fact is that over history we have made many such forecasts which have missed their mark by miles – Schumpeter’s 1943 observation that “Forecasts of future populations, from those of the seventeenth century on, were practically always wrong” remains as valid today.
It is true that society is ageing, but the rate of increase of longevity is far lower than the rate of growth of output, GDP. We have, with the exception of occasional periods of recession, grown steadily wealthier, and as we grow wealthier so, by choice, we spend more, both absolutely and proportionally, on education, healthcare and retirement. If we had, in their infancy, told today’s ninety year-old that their consumption at this age would be some eight times more in real terms than a ninety year-old at that time, we would have been summarily dismissed as over-optimistic to the point of certifiable madness.
