Thirdly, it seems upon every supposition improper to say that the labour of artificers, manufacturers, and merchants does not increase the real revenue of the society.Though we should suppose, for example, as it seems to be supposed in this system, that the value of the daily, monthly, and yearly consumption of this class was exactly equal to that of its daily, monthly, and yearly production, yet it would not from thence follow that its labour added nothing to the real revenue, to the real value of the annual produce of the land and labour of the society.An artificer, for example, who, in the first six months after harvest, executes ten pounds' worth of work, though he should in the same time consume ten pounds' worth of corn and other necessaries, yet really adds the value of ten pounds to the annual produce of the land and labour of the society.While he has been consuming a half-yearly revenue of ten pounds' worth of corn and other necessaries, he has produced an equal value of work capable of purchasing, either to himself or some other person, an equal half-yearly revenue.The value, therefore, of what has been consumed and produced during these six months is equal, not to ten, but to twenty pounds.It is possible, indeed, that no more than ten pounds' worth of this value may ever have existed at any one moment of time.But if the ten pounds' worth of corn and other necessaties, which were consumed by the artificer, had been consumed by a soldier or by a menial servant, the value of that part of the annual produce which existed at the end of the six months would have been ten pounds less than it actually is in consequence of the labour of the artificer.Though the value of what the artificer produces, therefore, should not at any one moment of time be supposed greater than the value he consumes, yet at every moment of time the actually existing value of goods in the market is, in consequence of what he produces, greater than it otherwise would be.
When the patrons of this system assert that the consumption of artificers, manufacturers, and merchants is equal to the value of what they produce, they probably mean no more than that their revenue, or the fund destined for their consumption, is equal to it.But if they had expressed themselves more accurately, and only asserted that the revenue of this class was equal to the value of what they produced, it might readily have occurred to the reader that what would naturally be saved out of this revenue must necessarily increase more or less the real wealth of the society.In order, therefore, to make out something like an argument, it was necessary that they should express themselves as they have done; and this argument, even supposing things actually were as it seems to presume them to be, turns out to be a very inconclusive one.
Fourthly, farmers and country labourers can no more augment, without parsimony, the real revenue, the annual produce of the land and labour of their society, than artificers, manufacturers, and merchants.The annual produce of the land and labour of any society can be augmented only in two ways; either, first, by some improvement in the productive powers of the useful labour actually maintained within it; or, secondly, by some increase in the quantity of that labour.
The improvement in the productive powers of useful labour depend, first, upon the improvement in the ability of the workman; and, secondly, upon that of the machinery with which he works.But the labour of artificers and manufacturers, as it is capable of being more subdivided, and the labour of each workman reduced to a greater simplicity of operation than that of farmers and country labourers, so it is likewise capable of both these sorts of improvements in a much higher degree.In this respect, therefore, the class of cultivators can have no sort of advantage over that of artificers and manufacturers.
The increase in the quantity of useful labour actually employed within any society must depend altogether upon the increase of the capital which employs it; and the increase of that capital again must be exactly equal to the amount of the savings from the revenue, either of the particular persons who manage and direct the employment of that capital, or of some other persons who lend it to them.If merchants, artificers, and manufacturers are, as this system seems to suppose, naturally more inclined to parsimony and saving than proprietors and cultivators, they are, so far, more likely to augment the quantity of useful labour employed within their society, and consequently to increase its real revenue, the annual produce of its land and labour.
