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 10_l._ 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 10_l._; their situation would be no better than if no such rise took place. If the hosier sold his stockings for 110_l._ instead of 100_l._, 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.
