Although a greater value is produced, a greater proportion of what remains of that value, after paying rent, is consumed by the producers, and it is this, and this alone, which regulates profits. Whilst the land yields abundantly, wages may temporarily rise, and the producers may consume more than their accustomed proportion; but the stimulus which will thus be given to population, will speedily reduce the labourers to their usual consumption. But when poor lands are taken into cultivation, or when more capital and labour are expended on the old land, with a less return of produce, the effect must be permanent. A greater proportion of that part of the produce which remains to be divided, after paying rent, between the owners of stock and the labourers, will be apportioned to the latter. Each man may, and probably will, have a less absolute quantity; but as more labourers are employed in proportion to the whole produce retained by the farmer, the value of a greater proportion of the whole produce will be absorbed by wages, and consequently the value of a smaller proportion will be devoted to profits. This will necessarily be rendered permanent by the laws of nature, which have limited the productive powers of the land.
Thus we again arrive at the same conclusion which we have before attempted to establish:—that in all countries, and at all times, profits depend on the quantity of labour requisite to provide necessaries for the labourers, on that land or with that capital which yields no rent. The effects then of accumulation will be different in different countries, and will depend chiefly on the fertility of the land. However extensive a country may be where the land is of a poor quality, and where the importation of food is prohibited, the most moderate accumulations of capital will be attended with great reductions in the rate of profit, and a rapid rise in rent; and on the contrary a small but fertile country, particularly if it freely permits the importation of food, may accumulate a large stock of capital without any great diminution in the rate of profits, or any great increase in the rent of land. In the Chapter on Wages, we have endeavoured to shew that the money price of commodities would not be raised by a rise of wages, either on the supposition that gold, the standard of money, was the produce of this country, or that it was imported from abroad. But if it were otherwise, if the prices of commodities were permanently raised by high wages, the proposition would not be less true, which asserts that high wages invariably affect the employers of labour, by depriving them of a portion of their real profits. Supposing the hatter, the hosier, and the shoemaker, each paid 10l. more wages in the manufacture of a particular quantity of their commodities, and that the price of hats, stockings, and shoes, rose by a sum sufficient to repay the manufacturer the 10l.; their situation would be no better than if no such rise took place. If the hosier sold his stockings for 110l. instead of 100l., his profits would be precisely the same money amount as before; but as he would obtain in exchange for this equal sum, one tenth less of hats, shoes, and every other commodity, and as he could with his former amount of savings employ fewer labourers at the increased wages, and purchase fewer raw materials at the increased prices, he would be in no better situation than if his money profits had been really diminished in amount, and every thing had remained at its former price. Thus then I have endeavoured to shew, first, that a rise of wages would not raise the price of commodities, but would invariably lower profits; and secondly, that if the prices of commodities could be raised, still the effect on profits would be the same; and that in fact the value of the medium only in which prices and profits are estimated would be lowered.
CHAPTER VI.
ON FOREIGN TRADE.
No extension of foreign trade will immediately increase the amount of value in a country, although it will very powerfully contribute to increase the mass of commodities, and therefore the sum of enjoyments. As the value of all foreign goods is measured by the quantity of the produce of our land and labour, which is given in exchange for them, we should have no greater value, if by the discovery of new markets, we obtained double the quantity of foreign goods in exchange for a given quantity of ours. If by the purchase of English goods to the amount of 1000l. a merchant can obtain a quantity of foreign goods, which he can sell in the English market for 1,200l., he will obtain 20 per cent. profit by such an employment of his capital; but neither his gains, nor the value of the commodities imported, will be increased or diminished by the greater or smaller quantity of foreign goods obtained. Whether, for example, he imports twenty-five or fifty pipes of wine, his interest can be no way affected, if at one time the twenty-five pipes, and at another the fifty pipes, equally sell for 1,200l. In either case his profit will be limited to 200l., or 20 per cent. on his capital; and in either case the same value will be imported into England. If the fifty pipes sold for more than 1,200l., the profits of this individual merchant would exceed the general rate of profits, and capital would naturally flow into this advantageous trade, till the fall of the price of wine had brought every thing to the former level.
It has indeed been contended, that the great profits which are sometimes made by particular merchants in foreign trade, will elevate the general rate of profits in the country, and that the abstraction of capital from other employments, to partake of the new and beneficial foreign commerce, will raise prices generally, and thereby increase profits. It has been said, by high authority, that less capital being necessarily devoted to the growth of corn, to the manufacture of cloth, hats, shoes, &c. while the demand continues the same, the price of these commodities will be so increased, that the farmer, hatter, clothier, and shoemaker, will have an increase of profits, as well as the foreign merchant.[13]
They who hold this argument agree with me, that the profits of different employments have a tendency to conform to one another; to advance and recede together. Our variance consists in this: They contend, that the equality of profits will be brought about by the general rise of profits; and I am of opinion, that the profits of the favoured trade will speedily subside to the general level.
For, first, I deny that less capital will necessarily be devoted to the growth of corn, to the manufacture of cloth, hats, shoes, &c., unless the demand for these commodities be diminished; and if so, their price will not rise. In the purchase of foreign commodities, either the same, a larger, or a less portion of the produce of the land and labour of England will be employed. If the same portion be so employed, then will the same demand exist for cloth, shoes, corn, and hats, as before, and the same portion of capital will be devoted to their production. If, in consequence of the price of foreign commodities being cheaper, a less portion of the annual produce of the land and labour of England is employed in the purchase of foreign commodities, more will remain for the purchase of other things. If there be a greater demand for hats, shoes, corn, &c. than before, which there may be, the consumers of foreign commodities having an additional portion of their revenue disposable, the capital is also disposable with which the greater value of foreign commodities was before purchased; so that with the increased demand for corn, shoes, &c. there exists also the means of procuring an increased supply, and therefore neither prices nor profits can permanently rise. If more of the produce of the land and labour of England be employed in the purchase of foreign commodities, less can be employed in the purchase of other things, and therefore fewer hats, shoes, &c. will be required. At the same time that capital is liberated from the production of shoes, hats, &c. more must be employed in manufacturing those commodities with which foreign commodities are purchased; and consequently in all cases the demand for foreign and home commodities together, as far as regards value, is limited by the revenue and capital of the country. If one increases, the other must diminish. If the importation of wine, given in exchange for the same quantity of English commodities be doubled, the people of England can either consume double the quantity of wine that they did before, or the same quantity of wine and a greater quantity of English commodities. If my revenue had been 1000l., with which I purchased annually one pipe of wine for 100l. and a certain quantity of English commodities for 900l.; when wine fell to 50l. per pipe, I might lay out the 50l. saved, either in the purchase of an additional pipe of wine, or in the purchase of more English commodities. If I bought more wine, and every wine-drinker did the same, the foreign trade would not be in the least disturbed; the same quantity of English commodities would be exported in exchange for wine, and we should receive double the quantity, though not double the value of wine. But if I, and others contented ourselves with the same quantity of wine as before, fewer English commodities would be exported, and the wine-drinkers might either consume the commodities which were before exported, or any others for which they had an inclination. The capital required for their production would be supplied by the capital liberated from the foreign trade.
