The issue of distribution isn't going to go away

The view that a falling birth rate is a ‘problem’ which needs to be addressed might be being expressed most forcibly by the political ‘right’, but it isn’t confined to that wing, as evidenced by this article last week from Polly Toynbee in the Guardian. Whilst (justifiably) demolishing the arguments of some Reform Ltd figures, she ends up agreeing with the objective (increasing the birth rate) but giving a different rationale.

There is a fringe element amongst those who support increased birth rates which is tinged with both misogyny (men controlling the fertility rate of women) and racism (a belief that the ‘solution’ to the economic drivers of immigration is to produce more native-born workers). Given the roughly twenty-year lead time involved in producing more workers, the latter is economic nonsense, but then racism and xenophobia have never been about logic or economics.

More seriously, the economic case for increasing birth rates revolves around the fact that the ratio of ‘productive’ to ‘unproductive’ adults is changing as the population ages. In an economy built around the assumption that the product of economic activity belongs to those engaged in it rather than to society as a whole, the fact that there is a problem is undeniable. Fewer workers supporting more non-workers – with no other changes to the economic model – will clearly lead to difficulties. Rebalancing the ratio by increasing the supply of people, even if we ignore the 20-year lead time, turns it into something of a Ponzi scheme, in which any increase in life expectancy (generally a good thing) has to be balanced by an increase in population size (not such a good thing in a finite world where resources are already being exploited unsustainably). Another solution, pursued in the UK by governments of both colours, is to reduce the number of non-workers by making people work longer. That would certainly rebalance the ratio and cut the cost of maintaining retirees: fewer pensioners = lower pension costs. But it also makes retirement (and even more so, a lengthy and healthy one) increasingly a privilege for those who have good occupational pensions and are not doing physically demanding work. It’s a ‘solution’, in short, which favours the better-off at the expense of the less well-off.

There is another approach, but it involves a change in paradigm – a shift away from seeing the output of economic activity as belonging only to those actively engaged in economic activity. If, instead, we see the ‘economy’ as being something which belongs to the whole of the society in which it operates, then the question becomes one of how the output of that economic activity is used within that society. A properly functioning society (including the economy which is part of it) needs to meet the needs of all its members – old, young, sick, and disabled members as well as productive workers. The idea that we only need to worry about how big the pie is, rather than how it is shared, has validity only so long as any increase in the size of the pie is both sustainable in terms of its use of finite resources, and equitable in terms of how the extra pie is used. Falling back on ‘growth’ in the abstract – the default position of Labour, Tory, Lib Dem and Reform Ltd politicians alike – is thus no solution at all if, as is the case at present, that growth is not only not sustainable within the resources available, but also the benefits are overwhelmingly captured by a tiny proportion of the population. We cannot simply avoid indefinitely the question of distribution.
