The labour of artificers and manufacturers never adds any thing to the value of the whole annual amount of the rude produce of the land. It adds, indeed, greatly to the value of some particular parts of it. But the consumption which, in the mean time, it occasions of other parts, is precisely equal to the value which it adds to those parts; so that the value of the whole amount is not, at any one moment of time, in the least augmented by it. The person who works the lace of a pair of fine ruffles for example, will sometimes raise the value of, perhaps, a pennyworth of flax to £30 sterling. But though, at first sight, he appears thereby to multiply the value of a part of the rude produce about seven thousand and two hundred times, he in reality adds nothing to the value of the whole annual amount of the rude produce. The working of that lace costs him, perhaps, two years labour. The £30 which he gets for it when it is finished, is no more than the repayment of the subsistence which he advances to himself during the two years that he is employed about it. The value which, by every day’s, month’s, or year’s labour, he adds to the flax, does no more than replace the value of his own consumption during that day, month, or year. At no moment of time, therefore, does he add any thing to the value of the whole annual amount of the rude produce of the land: the portion of that produce which he is continually consuming, being always equal to the value which he is continually producing. The extreme poverty of the greater part of the persons employed in this expensive, though trifling manufacture, may satisfy us that the price of their work does not, in ordinary cases, exceed the value of their subsistence. It is otherwise with the work of farmers and country labourers. The rent of the landlord is a value which, in ordinary cases, it is continually producing over and above replacing, in the most complete manner, the whole consumption, the whole expense laid out upon the employment and maintenance both of the workmen and of their employer.
Artificers, manufacturers, and merchants, can augment the revenue and wealth of their society by parsimony only; or, as it is expressed in this
