The Economist notes that Westerners may need to work longer as a result of increasing life-spans:
In some European countries the average retirement lasts more than a quarter of a century. In America the official pension age is 66, but the average American retires at 64 and can then expect to live for another 16 years. Average spending on public pensions across the OECD is now the equivalent of more than 7% of GDP (they cost America just 0.2% back in 1935). In some countries the current figure could double by 2050, to say nothing of the cost of private pensions and extra spending on health and long-term care…
Whether we like it or not, we are going back to the pre-Bismarckian world, where work had no formal stopping point. That reversion will not happen overnight, but preparations should start now—to ensure that when the inevitable happens it is a change for the better.
It should be for the better because it is being partly driven by a wonderful thing: people are living ever longer. Life expectancy has been rising by two or three years for every ten that pass, despite repeated forecasts that it was about to reach its limit. Centenarians used to be rarer than hens’ teeth; now America alone has 100,000 of them. By the end of this century the age of 100 may have become the new three score and ten.
This imminent greying of society is compounded by two other demographic shifts. First, in most rich countries women no longer have enough babies to keep up the numbers (a prospect that may please a lot of greens but not many governments); and the huge baby-boom generation, born after the second world war, has begun to retire. In 1950 the OECD countries had seven people aged 20–64 for every one of 65 and over. Now it is four to one—and on course to be two to one by 2050. That will ruin the pay-as-you-go state pension schemes that provide the bulk of retirement income in rich countries.
Unless I am lucky enough to win the lottery someday (not that I play), retirement sounds like another circle of hell. I could not spend years not being productive. I enjoy it. Besides, I, like most people of my generation, were already skeptical that we would ever be able to retire or that Social Security will even exist in the United States in forty years.
But the greying of the Western world might harm society in more-significant ways than the alleged death of retirement. See here for worrying scenarios of future intergenerational warfare.
