According to popular legend, the science of economics was christened “the dismal science” by Thomas Carlyle following the publication by Thomas Malthus in 1798 of “An Essay on the Principle of Population”. In this he suggested that poverty and hunger would be a country’s natural state since increases in population would tend to outstrip increases in food supply. Fortunately he was proved wrong as birth rates fell and new techniques increased the supply of food and the science of economics moved on.
We are currently focused on short-term issues such as Brexit but it is worth taking a longer perspective following the publication of a report in ‘The Lancet’ which has highlighted falling fertility rates across the world between 1950 and 2017. The reasons behind the fall include better education and employment prospects for women, improved access to contraception, better maternal education for mothers and prospective mothers and improvements in infant mortality. As a result, 91 out of 195 countries have been identified as having a fertility rate below 2.05 – the minimum necessary for stable population growth. For example, in Britain over the period, the fertility rate fell from 2.2 to 1.7.
The implications of falling fertility rates in richer countries, partially masked by inward immigration, focus on the conflict between increased life expectancy, creating an increased number of elderly pensioners receiving benefits and increasingly needing expensive medical care, and a falling supply of workers who are paying taxes to support the elderly. These workers will therefore face a greater burden in terms of the taxes they will need to pay to support the elderly.
This is already significant in Japan where 28% of the population are over 65, the highest proportion in the world, compared with 18% in the UK and 22% in Germany. One offsetting feature in Japan is that people often work on beyond their retirement age – 3% of their labour force is over 80! Although it is not suggested that working until 80 becomes the norm, the retirement age in many countries is being increased as a result of increased life expectancy and, in the UK, it will reach 66 by October 2020 and 67 by 2028 for both men and women. This will reduce pension payments and increase tax revenue but, alone, is unlikely to be enough to prevent developed countries facing increasing budget deficits to finance care and benefits for the elderly.
As this crisis unfolds, the people who will suffer most are not the elderly but younger generations who will not only be working longer and paying higher taxes but will face student debt and higher house prices than experienced by their grandparents
