It happens, indeed, sometimes, that from bad government, extravagant habits, and a faulty constitution of society, the accumulation of capital is stopped, while fertile land is in considerable plenty, in which case profits may continue permanently very high; but even in this case wages must necessarily fall, which by reducing the expenses of cultivation must occasion rents.  There is nothing so absolutely unavoidable in the progress of society as the fall of wages, that is such a fall as, combined with the habits of the labouring classes, will regulate the progress of population according to the means of subsistence.  And when, from the want of an increase of capital, the increase of produce is checked, and the means of subsistence come to a stand, the wages of labour must necessarily fall so low, as only just to maintain the existing population, and to prevent any increase.

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.
