We observe in consequence, that in all those countries, such as Poland, where, from the want of accumulation, the profits of stock remain very high, and the progress of cultivation either proceeds very slowly, or is entirely stopped, the wages of labour are extremely low. And this cheapness of labour, by diminishing the expenses of cultivation, as far as labour is concerned, counteracts the effects of the high profits of stock, and generally leaves a larger rent to the landlord than in those countries, such as America, where, by a rapid accumulation of stock, which can still find advantageous employment, and a great demand for labour, which is accompanied by an adequate increase of produce and population, profits cannot be low, and labour for some considerable time remains very high.
It may be laid down, therefore, as an incontrovertible truth, that as a nation reaches any considerable degree of wealth, and any considerable fullness of population, which of course cannot take place without a great fall both in the profits of stock and the wages of labour, the separation of rents, as a kind of fixture upon lands of a certain quality, is a law as invariable as the action of the principle of gravity. And that rents are neither a mere nominal value, nor a value unnecessarily and injuriously transferred from one set of people to another; but a most real and essential part of the whole value of the national property, and placed by the laws of nature where they are, on the land, by whomsoever possessed, whether the landlord, the crown, or the actual cultivator.
Rent then has been traced to the same common nature with that general surplus from the land, which is the result of certain qualities of the soil and its products; and it has been found to commence its separation from profits, as soon as profits and wages fall, owing to the comparative scarcity of fertile land in the natural progress of a country towards wealth and population.
Having examined the nature and origin of rent, it remains for us to consider the laws by which it is governed, and by which its increase or decrease is regulated.
When capital has accumulated, and labour fallen on the most eligible lands of a country, other lands less favourably circumstanced with respect to fertility or situation, may be occupied with advantage. The expenses of cultivation, including profits, having fallen, poorer land, or land more distant from markets, though yielding at first no rent, may fully repay these expenses, and fully answer to the cultivator. And again, when either the profits of stock or the wages of labour, or both, have still further fallen, land still poorer, or still less favourably situated, may be taken into cultivation. And, at every step, it is clear, that if the price of produce does not fall, the rents of land will rise. And the price of produce will not fall, as long as the industry and ingenuity of the labouring classes, assisted by the capitals of those not employed upon the land, can find something to give in exchange to the cultivators and landlords, which will stimulate them to continue undiminished their agricultural exertions, and maintain their increasing excess of produce.
In tracing more particularly the laws which govern the rise and fall of rents, the main causes which diminish the expenses of cultivation, or reduce the cost of the instruments of production, compared with the price of produce, require to be more specifically enumerated. The principal of these seem to be four:
first, such an accumulation of capital as will lower the profits of stock; secondly, such an increase of population as will lower the wages of labour; thirdly, such agricultural improvements, or such increase of exertions, as will diminish the number of labourers necessary to produce a given effect; and fourthly, such an increase in the price of agricultural produce, from increased demand, as without nominally lowering the expense of production, will increase the difference between this expense and the price of produce.
The operation of the three first causes in lowering the expenses of cultivation, compared with the price of produce, are quite obvious; the fourth requires a few further observations.
If a great and continued demand should arise among surrounding nations for the raw produce of a particular country, the price of this produce would of course rise considerably; and the expenses of cultivation, rising only slowly and gradually to the same proportion, the price of produce might for a long time keep so much ahead, as to give a prodigious stimulus to improvement, and encourage the employment of much capital in bringing fresh land under cultivation, and rendering the old much more productive.
Nor would the effect be essentially different in a country which continued to feed its own people, if instead of a demand for its raw produce, there was the same increasing demand for its manufactures. These manufactures, if from such a demand the value of their amount in foreign countries was greatly to increase, would bring back a great increase of value in return, which increase of value could not fail to increase the value of the raw produce. The demand for agricultural as well as manufactured produce would be augmented; and a considerable stimulus, though not perhaps to the same extent as in the last case, would be given to every kind of improvement on the land.
A similar effect would be produced by the introduction of new machinery, and a more judicious division of labour in manufactures. It almost always happens in this case, not only that the quantity of manufactures is very greatly increased, but that the value of the whole mass is augmented, from the great extension of the demand for them, occasioned by their cheapness.
