The Wealth of Nations

It has been shown in the First Book, that the price of the greater part of commodities resolves itself into three parts, of which one pays the wages of the labour, another the profits of the stock, and a third the rent of the land which had been employed in producing and bringing them to market: that there are, indeed, some commodities of which the price is made up of two of those parts only, the wages of labour, and the profits of stock; and a very few in which it consists altogether in one, the wages of labour; but that the price of every commodity necessarily resolves itself into some one or other, or all, of those three parts; every part of it which goes neither to rent nor to wages, being necessarily profit to some body. Since this is the case, it has been observed, with regard to every particular commodity, taken separately, it must be so with regard to all the commodities which compose the whole annual produce of the land and labour of every country, taken complexly. The whole price or exchangeable value of that annual produce must resolve itself into the same three parts, and be parcelled out among the different inhabitants of the country, either as the wages of their labour, the profits of their stock, or the rent of their land. But though the whole value of the annual produce of the land and labour of every country, is thus divided among, and constitutes a revenue to, its different inhabitants; yet, as in the rent of a private estate, we distinguish between the gross rent and the neat rent, so may we likewise in the revenue of all the inhabitants of a great country. The gross rent of a private estate comprehends whatever is paid by the farmer; the neat rent, what remains free to the landlord, after deducting the expense of management, of repairs, and all other necessary charges; or what, without hurting his estate, he can afford to place in his stock reserved for immediate consumption, or to spend upon his table, equipage, the ornaments of his house and furniture, his private enjoyments and amusements. His real wealth is in proportion, not to his gross, but to his neat rent. The gross revenue of all the inhabitants of a great country comprehends the whole annual produce of their land and labour; the neat revenue, what remains free to them, after deducting the expense of maintaining first, their fixed, and, secondly, their circulating capital, or what, without encroaching upon their capital, they can place in their stock reserved for immediate consumption, or spend upon their subsistence, conveniencies, and amusements. Their real wealth, too, is in proportion, not to their gross, but to their neat revenue. The whole expense of maintaining the fixed capital must evidently be excluded from the neat revenue of the society. Neither the materials necessary for supporting their useful machines and instruments of trade, their profitable buildings, etc. nor the produce of the labour necessary for fashioning those materials into the proper form, can ever make any part of it. The price of that labour may indeed make a part of it; as the workmen so employed may place the whole value of their wages in their stock reserved for immediate consumption. But in other sorts of labour, both the price and the produce go to this stock; the price to that of the workmen, the produce to that of other people, whose subsistence, conveniencies, and amusements, are augmented by the labour of those workmen. The intention of the fixed capital is to increase the productive powers of labour, or to enable the same number of labourers to perform a much greater quantity of work. In a farm where all the necessary buildings, fences, drains, communications, etc. are in the most perfect good order, the same number of labourers and labouring cattle will raise a much greater produce, than in one of equal extent and equally good ground, but not furnished with equal conveniencies. In manufactures, the same number of hands, assisted with the best machinery, will work up a much greater quantity of goods than with more imperfect instruments of trade. The expense which is properly laid out upon a fixed capital of any kind, is always repaid with great profit, and increases the annual produce by a much greater value than that of the support which such improvements require. This support, however, still requires a certain portion of that produce. A certain quantity of materials, and the labour of a certain number of workmen, both of which might have been immediately employed to augment the food, clothing, and lodging, the subsistence and conveniencies of the society, are thus diverted to another employment, highly advantageous indeed, but still different from this one. It is upon this account that all such improvements in mechanics, as enable the same number of workmen to perform an equal quantity of work with cheaper and simpler machinery than had been usual before, are always regarded as advantageous to every society. A certain quantity of materials, and the labour of a certain number of workmen, which had before been employed in supporting a more complex and expensive machinery, can afterwards be applied to augment the quantity of work which that or any other machinery is useful only for performing. The undertaker of some great manufactory, who employs a thousand a-year in the maintenance of his machinery, if he can reduce this expense to five hundred, will naturally employ the other five hundred in purchasing an additional quantity of materials, to be wrought up by an additional number of workmen. The quantity of that work, therefore, which his machinery was useful only for performing, will naturally be augmented, and with it all the advantage and conveniency which the society can derive from that work. The expense of maintaining the fixed capital in a great country, may very properly be compared to that of repairs in a private estate. The expense of repairs may frequently be necessary for supporting the produce of the estate, and consequently both the gross and the neat rent of the landlord. When by a more proper direction, however, it can be diminished without occasioning any diminution of produce, the gross rent remains at least the same as before, and the neat rent is necessarily augmented. But though the whole expense of maintaining the fixed capital is thus necessarily excluded from the neat revenue of the society, it is not the same case with that of maintaining the circulating capital. Of the four parts of which this latter capital is composed, money, provisions, materials, and finished work, the three last, it has already been observed, are regularly withdrawn from it, and placed either in the fixed capital of the society, or in their stock reserved for immediate consumption. Whatever portion of those consumable goods is not employed in maintaining the former, goes all to the latter, and makes a part of the neat revenue of the society. The maintenance of those three parts of the circulating capital, therefore, withdraws no portion of the annual produce from the neat revenue of the society, besides what is necessary for maintaining the fixed capital. The circulating capital of a society is in this respect different from that of an individual. That of an individual is totally excluded from making any part of his neat revenue, which must consist altogether in his profits. But though the circulating capital of every individual makes a part of that of the society to which he belongs, it is not upon that account totally excluded from making a part likewise of their neat revenue. Though the whole goods in a merchant’s shop must by no means be placed in his own stock reserved for immediate consumption, they may in that of other people, who, from a revenue derived from other funds, may regularly replace their value to him, together with its profits, without occasioning any diminution either of his capital or of theirs. Money, therefore, is the only part of the circulating capital of a society, of which the maintenance can occasion any diminution in their neat revenue. The fixed capital, and that part of the circulating capital which consists in money, so far as they affect the revenue of the society, bear a very great resemblance to one another. First, as those machines and instruments of trade, etc. require a certain expense, first to erect them, and afterwards to support them, both which expenses, though they make a part of the gross, are deductions from the neat revenue of the society; so the stock of money which circulates in any country must require a certain expense, first to collect it, and afterwards to support it; both which expenses, though they make a part of the gross, are, in the same manner, deductions from the neat revenue of the society. A certain quantity of very valuable materials, gold and silver, and of very curious labour, instead of augmenting the stock reserved for immediate consumption, the subsistence, conveniencies, and amusements of individuals, is employed in supporting that great but expensive instrument of commerce, by means of which every individual in the society has his subsistence, conveniencies, and amusements, regularly distributed to him in their proper proportions. Secondly, as the machines and instruments of trade, etc. which compose the fixed capital either of an individual or of a society, make no part either of the gross or of the neat revenue of either; so money, by means of which the whole revenue of the society is regularly distributed among all its different members, makes itself no part of that revenue. The great wheel of circulation is altogether different from the goods which are circulated by means of it. The revenue of the society consists altogether in those goods, and not in the wheel which circulates them. In computing either the gross or the neat revenue of any society, we must always, from the whole annual circulation of money and goods, deduct the whole value of the money, of which not a single farthing can ever make any part of either. It is the ambiguity of language only which can make this proposition appear either doubtful or paradoxical. When properly explained and understood, it is almost self-evident. When we talk of any particular sum of money, we sometimes mean nothing but the metal pieces of which it is composed, and sometimes we include in our meaning some obscure reference to the goods which can be had in exchange for it, or to the power of purchasing which the possession of it conveys. Thus, when we say that the circulating money of England has been computed at eighteen millions, we mean only to express the amount of the metal pieces, which some writers have computed, or rather have supposed, to circulate in that country. But when we say that a man is worth fifty or a hundred pounds a-year, we mean commonly to express, not only the amount of the metal pieces which are annually paid to him, but the value of the goods which he can annually purchase or consume; we mean commonly to ascertain what is or ought to be his way of living, or the quantity and quality of the necessaries and conveniencies of life in which he can with propriety indulge himself. When, by any particular sum of money, we mean not only to express the amount of the metal pieces of which it is composed, but to include in its signification some obscure reference to the goods which can be had in exchange for them, the wealth or revenue which it in this case denotes, is equal only to one of the two values which are thus intimated somewhat ambiguously by the same word, and to the latter more properly than to the former, to the money’s worth more properly than to the money. Thus, if a guinea be
