communities. It is to the emigration of English capital, that we have chiefly to look for keeping up a supply of cheap food and cheap materials of clothing, proportional to the increase of our population; thus enabling an increasing capital to find employment in the country, without reduction of profit, in producing manufactured articles with which to pay for this supply of raw produce. Thus, the exportation of capital is an agent of great efficacy in extending the field of employment for that which remains: and it may be said truly that, up to a certain point, the more capital we send away, the more we shall possess and be able to retain at home.
In countries which are further advanced in industry and population, and have therefore a lower rate of profit, than others, there is always, long before the actual minimum is reached, a practical minimum, viz., when profits have fallen so much below what they are elsewhere, that, were they to fall lower, all further accumulations would go abroad. In the present state of the industry of the world, when there is occasion, in any rich and improving country, to take the minimum of profits at all into consideration for practical purposes, it is only this practical minimum that needs be considered. As long as there are old countries where capital increases very rapidly, and new countries where profit is still high, profits in the old countries will not sink to the rate which would put a stop to accumulation; the fall is stopped at the point which sends capital abroad. It is only, however, by improvements in production, and even in the production of things consumed by labourers, that the capital of a country like England is prevented from speedily reaching that degree of lowness of profit, which would cause all further savings to be sent to find employment in the colonies, or in foreign countries.1 CHAPTER V
1 [See Appendix CC. The Tendency of Profits to a Minimum.]
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 a§ 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.1 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 bond 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
