“Malthus, the originator of this doctrine, maintains that population is always pressing on the means of subsistence; that as soon as production increases, population increases in the same proportion; and that the inherent tendency of the population to multiply in excess of the available means of subsistence is the root of all misery and all vice. For, when there are too many people, they have to be disposed of in one way or another: either they must be killed by violence or they must starve. But when this has happened, there is once more a gap which other multipliers of the population immediately start to fill up once more: and so the old misery begins all over again. … The implications of this line of thought are that since it is precisely the poor who are the surplus, nothing should be done for them except to make their dying of starvation as easy as possible, and to convince them that it cannot be helped and that there is no other salvation for their whole class than keeping propagation down to the absolute minimum. Or if this proves impossible, then it is after all better to establish a state institution for the painless killing of the children of the poor .. whereby each working-class family would be allowed to have two and a half children, any excess being painlessly killed. Charity is to be considered a crime, since it supports the augmentation of the surplus population. Indeed, it will be very advantageous to declare poverty a crime and to turn poor-houses into prisons, as has already happened in England as a result of the new “liberal” Poor Law.
Am I to go on any longer elaborating this vile, infamous theory, this hideous blasphemy against nature and mankind? Am I to pursue its consequences any further? Here at last we have the immorality of the economist brought to its highest pitch. What are all the wars and horrors of the monopoly system compared with this theory! …
If Malthus had not considered the matter so one-sidedly, he could not have failed to see that surplus population or labour-power is invariably tied up with surplus wealth, surplus capital and surplus landed property. The population is only too large where the productive power as a whole is too large. The condition of every over-populated country, particularly England, since the time when Malthus wrote, makes this abundantly clear. These were the facts which Malthus ought to have considered in their totality, and whose consideration was bound to have led to the correct conclusion. Instead, he selected one fact, gave no consideration to the others, and therefore arrived at his crazy conclusion.
The second error he committed was to confuse means of subsistence with [means of] employment. That population is always pressing on the means of employment – that the number of people produced depends on the number of people who can be employed – in short, that the production of labour-power has been regulated so far by the law of competition and is therefore also exposed to periodic crises and fluctuations – this is a fact whose establishment constitutes Malthus’ merit. But the means of employment are not the means of subsistence. Only in their end-result are the means of employment increased by the increase in machine-power and capital. The means of subsistence increase as soon as productive power increases even slightly. Here a new contradiction in economics comes to light. The economist’s “demand” is not the real demand; his “consumption” is an artificial consumption. For the economist, only that person really demands, only that person is a real consumer, who has an equivalent to offer for what he receives. But if it is a fact that every adult produces more than he himself can consume, that children are like trees which give superabundant returns on the outlays invested in them – and these certainly are facts, are they not? – then it must be assumed that each worker ought to be able to produce far more than he needs and that the community, therefore, ought to be very glad to provide him with everything he needs; one must consider a large family to be a very welcome gift for the community. But the economist, with his crude outlook, knows no other equivalent than that which is paid to him in tangible ready cash. He is so firmly set in his antitheses that the most striking facts are of as little concern to him as the most scientific principles.
We destroy the contradiction simply by transcending it. With the fusion of the interests now opposed to each other there disappears the contradiction between excess population here and excess wealth there; there disappears the miraculous fact (more miraculous than all the miracles of all the religions put together) that a nation has to starve from sheer wealth and plenty; and there disappears the crazy assertion that the earth lacks the power to feed men. …
At the same time, the Malthusian theory has certainly been a necessary point of transition which has taken us an immense step further. Thanks to this theory, as to economics as a whole, our attention has been drawn to the productive power of the earth and of mankind; and after overcoming this economic despair we have been made for ever secure against the fear of overpopulation. We derive from it the most powerful economic arguments for a social transformation. … Through this theory we have come to know the deepest degradation of mankind, their dependence on the conditions of competition. It has shown us how in the last instance private property has turned man into a commodity whose production and destruction also depend solely on demand; how the system of competition has thus slaughtered, and daily continues to slaughter, millions of men. All this we have seen, and all this drives us to the abolition of this degradation of mankind through the abolition of private property, competition and the opposing interests.
Yet, so as to deprive the universal fear of overpopulation of any possible basis, let us once more return to the relationship of productive power to population. Malthus establishes a formula on which he bases his entire system: population is said to increase in a geometrical progression – 1+2+4+8+16+32, etc.; the productive power of the land in an arithmetical progression – 1+2+3+4+5+6. The difference is obvious, is terrifying; but is it correct? Where has it been proved that the productivity of the land increases in an arithmetical progression? The extent of land is limited. All right! The labour-power to be employed on this land-surface increases with population. Even if we assume that the increase in yield due to increase in labour does not always rise in proportion to the labour, there still remains a third element which, admittedly, never means anything to the economist – science – whose progress is as unlimited and at least as rapid as that of population. What progress does the agriculture of this century owe to chemistry alone – indeed, to two men alone, Sir Humphry Davy and Justus Liebig! But science increases at least as much as population. The latter increases in proportion to the size of the previous generation, science advances in proportion to the knowledge bequeathed to it by the previous generation, and thus under the most ordinary conditions also in a geometrical progression. And what is impossible to science? But it is absurd to talk of over-population so long as “there is ‘enough waste land in the valley of the Mississippi for the whole population of Europe to be transplanted there”; so long as no more than one-third of the earth can be considered cultivated, and so long as the production of this third itself can be raised sixfold and more by the application of improvements already known.”
