CHAPTER V.
CONSEQUENCES OF THE TENDENCY OF PROFITS TO A MINIMUM.
§ 1.The theory of the effect of accumulation on profits, laid down in the preceding chapter, materially alters many of the practical conclusions which might otherwise be supposed to follow from the general principles of Political Economy, and which were, indeed, long admitted as true by the highest authorities on the subject.
It must greatly abate, or rather, altogether destroy, in countries where profits are low, the immense importance which used to be attached by political economists to the effects which an event or a measure of government might have in adding to or subtracting from the capital of the country. We have now seen that the lowness of profits is a proof that the spirit of accumulation is so active, and that the increase of capital has proceeded at so rapid a rate, as to outstrip the two counter-agencies, improvements in production, and increased supply of cheap necessaries from abroad: and that unless a considerable portion of the annual increase of capital were either periodically destroyed, or exported for foreign investment, the country would speedily attain the point at which further accumulation would cease, or at least spontaneously slacken, so as no longer to overpass the march of invention in the arts which produce the necessaries of life. In such a state of things as this, a sudden addition to the capital of the country, unaccompanied by any increase of productive power, would be but of transitory duration; since by depressing profits and interest, it would either diminish by a corresponding amount the savings which would be made from income in the year or two following, or it would cause an equivalent ​amount to be sent abroad, or to be wasted in rash speculations. Neither, on the other hand, would a sudden abstraction of capital, unless of inordinate amount, have any real effect in impoverishing the country. After a few months or years, there would exist in the country just as much capital as if none had been taken away. The abstraction, by raising profits and interest, would give a fresh stimulus to the accumulative principle, which would speedily fill up the vacuum. Probably, indeed, the only effect that would ensue, would be that for some time afterwards less capital would be exported, and less thrown away in hazardous speculation.
In the first place, then, this view of things greatly weakens, in a wealthy and industrious country, the force of the economical argument against the expenditure of public money for really valuable, even though industriously unproductive, purposes. If for any great object of justice or philanthropic policy, such as the industrial regeneration of Ireland, or a comprehensive measure of colonization or of public education, it were proposed to raise a large sum by way of loan, politicians need not demur to the abstraction of so much capital, as tending to dry up the permanent sources of the country's wealth, and diminish the fund which supplies the subsistence of the labouring population. The utmost expense which could be requisite for any of these purposes, would not in all probability deprive one labourer of employment, or diminish the next year's production by one ell of cloth or one bushel of grain. In poor countries, the capital of the country requires the legislator's sedulous care; he is bound to be most cautious of encroaching upon it, and should favour to the utmost its accumulation at home, and its introduction from abroad. But in rich, populous, and highly cultivated countries, it is not capital which is the deficient element, but fertile land; and what the legislator should desire and promote, is not a greater aggregate saving, but a greater return to savings, either by improved cultivation, or by access to the produce of more fertile lands in other parts of the ​globe. In such countries, the government may take any moderate portion of the capital of the country and expend it as revenue, without affecting the national wealth: the whole being either drawn from that portion of the annual savings which would otherwise be sent abroad, or being subtracted from the unproductive expenditure of individuals for the next year or two, since every million spent makes room for another million to be saved before reaching the overflowing point. When the object in view is worth the sacrifice of such an amount of the expenditure that furnishes the daily enjoyments of the people, the only well-grounded economical objection against taking the necessary funds directly from capital, consists of the inconveniences attending the process of raising a revenue by taxation, to pay the interest of a debt.
The same considerations enable us to throw aside as unworthy of regard, one of the common arguments against emigration as a means of relief for the labouring class. Emigration, it is said, can do no good to the labourers, if, in order to defray the cost, as much must be taken away from the capital of the country as from its population. That anything like this proportion could require to be abstracted from capital for the purpose even of the most extensive colonization, few, I should think, would now assert: but even on that untenable supposition, it is an error to suppose that no benefit would be conferred on the labouring class. If one-tenth of the labouring people of England were transferred to the colonies, and along with them one-tenth of the circulating capital of the country, either wages, or profits, or both, would be greatly benefited, by the diminished pressure of capital and population upon the fertility of the land. There would be a reduced demand for food: the inferior arable lands would be thrown out of cultivation, and would become pasture; the superior would be cultivated less highly, but with a greater proportional return; food would be lowered in price, and though money wages would not rise, every ​labourer would be considerably improved in circumstances, an improvement which, if no increased stimulus to population and fall of wages ensued, would be permanent; while if there did, profits would rise, and accumulation start forward so as to repair the loss of capital. The landlords alone would sustain some loss of income; and even they, only if colonization went to the length of actually diminishing capital and population, but not if it merely carried off the annual increase.
§ 2.From the same principles we are now able to arrive at a final conclusion respecting the effects which machinery, and generally the sinking of capital for a productive purpose, produce upon the immediate and ultimate interests of the labouring class. The characteristic property of this class of industrial improvements is the conversion of circulating capital into fixed: and it was shown in the first Book, that in a country where capital accumulates slowly, the introduction of machinery, permanent improvements of land, and the like, might be, for the time, extremely injurious; since the capital so employed might be directly taken from the wages fund, the subsistence of the people and the employment for labour curtailed, and the gross annual produce of the country actually diminished. But in a country of great annual savings and low profits, no such effects need be apprehended. Since even the emigration of capital, or its unproductive expenditure, or its absolute waste, do not in such a country, if confined within any moderate bounds, at all diminish the aggregate amount of the wages fund— still less can the mere conversion of a like sum into fixed capital, which continues to be productive, have that effect. It merely draws off at one orifice what was already flowing out at another; or if not, the greater vacant space left in the reservoir does but cause a greater quantity to flow in. Accordingly, in spite of the mischievous ​derangements of the money-market which were at one time occasioned by the sinking of great sums in railways, I was never able to agree with those who apprehended mischief, from this source, to the productive resources of the country. Not on the absurd ground (which to any one acquainted with the elements of the subject needs no confutation) that railway expenditure is a mere transfer of capital from hand to hand, by which nothing is lost or destroyed. This is true of what is spent in the purchase of the land; a portion too of what is paid to parliamentary agents, counsel, engineers, and surveyors, is saved by those who receive it, and becomes capital again: but what is laid out in the bonâ fide construction of the railway itself, is lost and gone; when once expended, it is incapable of ever being paid in wages or applied to the maintenance of labourers again; as a matter of account, the result is that so much food and clothing and tools have been consumed, and the country has got a railway instead. But what I would urge is, that sums so applied are mostly a mere appropriation of the annual overflowing which would otherwise have gone abroad, or been thrown away unprofitably, leaving neither a railway nor any other tangible result. The railway gambling of 1844 and 1845 probably saved the country from a depression of profits and interest, and a rise of all public and private securities, which would have engendered still wilder speculations, and when the effects came afterwards to be complicated by the scarcity of food, would have ended in a still more formidable crisis than was experienced in the years immediately following. In the poorer countries of Europe, the rage for railway construction might have had worse consequences than in England, were it not that in those countries such enterprises are in a great measure carried on by foreign capital. The railway operations of the various nations of the world may be looked upon as a sort of competition for the overflowing capital of the countries where profit is low and capital abundant, as England and Holland. The English railway speculations are a struggle to keep our annual increase ​of capital at home; those of foreign countries are an effort to obtain it.
It already appears from these considerations, that the conversion of circulating capital into fixed, whether by railways, or manufactories, or ships, or machinery, or canals, or mines, or works of drainage and irrigation, is not likely, in any rich country, to diminish the gross produce or the amount of employment for labour. How much then is the case strengthened, when we consider that these transformations of capital are of the nature of improvements in production, which, instead of ultimately diminishing circulating capital, are the necessary conditions of its increase, since they alone enable a country to possess a constantly augmenting capital without reducing profits to the rate which would cause accumulation to stop. There is hardly any increase of fixed capital which does not enable the country to contain eventually a larger circulating capital, than it otherwise could possess and employ within its own limits; for there is hardly any creation of fixed capital which, when it proves successful, does not cheapen the articles on which wages are habitually expended. All capital sunk in the permanent improvement of land, lessens the cost of food and materials; almost all improvements in machinery cheapen the labourer's clothing or lodging, or the tools with which these are made; improvements in locomotion, such as railways, cheapen to the consumer all things which are brought from a distance. All these improvements make the labourers better off with the. same money wages, better off if they do not increase their rate of multiplication. But if they do, and wages consequently fall, at least profits rise, and, while accumulation receives an immediate stimulus, room is made for a greater amount of capital before a sufficient motive arises for sending it abroad. Even the improvements which ​do not cheapen the things consumed by the labourer, and which, therefore, do not raise profits nor retain capital in the country, nevertheless, as we have seen, by lowering the minimum of profit for which people will ultimately consent to save, leave an ampler margin than previously for eventual accumulation, before arriving at the stationary state.
We may conclude, then, that improvements in production, and emigration of capital to the more fertile soils and unworked mines of the uninhabited or thinly peopled parts of the globe, do not, as appears to a superficial view, diminish the gross produce and the demand for labour at home; but, on the contrary, are what we have chiefly to depend on for increasing both, and are even the necessary conditions of any great or prolonged augmentation of either. Nor is it any exaggeration to say, that within certain, and not very narrow, limits, the more capital a country like England expends in these two ways, the more she will have left.
