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 ******r machinery than had been usual before, are always regarded as advantageous to every society.Acertain 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 net 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 net rent is necessarily augmented.
But though the whole expense of maintaining the fixed capital is thus necessarily excluded from the net 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 employed in maintaining the former, goes all to the latter, and makes a part of the net revenue of the society.The maintenance of those three parts of the circulating capital, therefore, withdraws no portion of the annual produce from the net 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 ****** any part of his net 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 ****** a part likewise of their net 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 net 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 net 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 net 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.
