From the original root-fallacy Malthus argued that poverty, prostitution, war, disease, and a high death-rate are necessary in order to keep down the population: and from the same false premises birth controllers are now arguing that a high birth-rate causes (1) poverty, and (2) a high death-rate. The steps in the argument whereby these amazing conclusions are reached are as follows. Before the death-rate can be lowered the social conditions of the people must be improved; if social conditions are improved there will be an enormous increase of population in geometrical progression; the food supply of the country and even of the world cannot be increased at the same rate; and therefore there will be greater poverty and a higher death-rate unless the birth-rate is lowered. Thus Malthusians argue. In view of the false premises on which their argument is based, it is not surprising to find that their deductions are erroneous and contain many economic and statistical fallacies, to the consideration of which we may now devote our attention.
Section 1. BIRTH-RATE AND POVERTY
The first false deduction of birth controllers is that a high birth-rate, by intensifying the struggle for existence, increases poverty. In order to bolster up this contention, Malthusians quote three arguments concerning (a) famines, (b) abundance, and (c) wages, and each of these arguments is fallacious.
(a) Famines
The prevalence of famines is quoted as a proof of reckless overpopulation. Now a famine may occur from several different causes, some within and others beyond the control of man, but a failure of crops has never yet been caused by pressure on the soil. On the contrary, famine is less likely to arise in a country whose soil is intensively cultivated, because intensive cultivation means a variety of crops, and therefore less risk of all the crops failing. Moreover, during the past century famine has occurred in Bengal, where population is dense; in Ireland, where population is moderate, and in Eastern Russia, where population is scanty. The existence of famine is therefore no proof that a country is overpopulated, although it may indicate that a country is badly governed or under-developed.
(b) Abundance
Malthusians also claim that by means of artificial birth control we could live in a land of abundance. They point out that, as the population of a new colony increases, the colonists, by applying the methods of civilisation to the rich soil, become more and more prosperous. Eventually there comes a time when capital or labour applied to the soil gives a maximum return per head of population. Once that point has been reached any further capital or labour applied to the soil will produce a smaller return per head of population. This "law of diminishing returns" may be illustrated by a simpler example. Let us suppose that during one year a market garden worked by one man has produced vegetables to the value of £10. During the second year the garden is worked by ten men and produces vegetables to the value of £200. It is obvious that the work of ten men has produced twice as much per head as the work of one man, because each man has produced not £10 but £20. During the third year the garden is worked by twenty men and yields vegetables to the value of £300. The total yield is greater, but the yield per head is less, because each man has produced not £20 but £15. The point of maximum production per head has been passed, and the law of diminishing returns is operating.
By restricting the birth-rate Malthusians would limit the population to the number necessary for maximum production per head. Now, in the first place, it would be very difficult, if not impossible, in the case of a country with various industries, to decide when the line of maximum production had been passed at any given time. Moreover, it would be utterly impossible to fix this line permanently. In the case of our market garden the introduction of intensive horticulture might mean that maximum production per head required the work of forty men. Again, the very phrase "maximum production per head" implies sterling moral qualities in the workers, and an absence of drones; and sterling moral qualities have never been prominent in any nation, once the practice of artificial birth control has been adopted. Lastly, the Christian ideal requires for its realisation, not a maximum, but an adequate supply of food, clothing, shelter, and fuel. Christianity teaches that to seek after the maximum enjoyment of material things is not the chief end of man, because the life of a man in this world is very short compared with his life in eternity.
(c) Wages
The Wages Fund Theory is an economic reflection of the Malthusian myth. This theory assumes that a definite fixed sum is available every year for distribution as wages amongst labourers, so that the more numerous the labourers the less wages will each one receive. From this theory Malthusians argue that the only remedy for low wages is artificial birth control. They carefully refrain from telling the working classes the other aspect of this Wages Fund theory—namely, that if the workers in one trade receive a rise in wages, a corresponding reduction must be made in the wages of others, so that a rise in wages here and there confers no real benefit on the labouring classes as a whole. That is merely one illustration of capitalist bias in the Malthusian propaganda. In any case, economic science has discarded the Wages Fund Theory as a pure fiction. No fixed or definite sum is available for wages, because the wages of a labourer are derived from the produce of his work. Even in the case of making a railway, where wages are paid before the work is completed, the money is advanced by shareholders on the security of the proceeds that will eventually accrue from the produce of the labourers.
