An Inquiry into the Nature and Causes of the Wealth of Nations

by Adam Smith

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 system, by privation, that is, by depriving themselves of a part of the funds destined for their own subsistence. They annually reproduce nothing but those funds. Unless, therefore, they annually save some part of them, unless they annually deprive themselves of the enjoyment of some part of them, the revenue and wealth of their society can never be, in the smallest degree, augmented by means of their industry. Farmers and country labourers, on the contrary, may enjoy completely the whole funds destined for their own subsistence, and yet augment, at the same time, the revenue and wealth of their society. Over and above what is destined for their own subsistence, their industry annually affords a neat produce, of which the augmentation necessarily augments the revenue and wealth of their society. Nations, therefore, which, like France or England, consist in a great measure, of proprietors and cultivators, can be enriched by industry and enjoyment. Nations, on the contrary, which, like Holland and Hamburgh, are composed chiefly of merchants, artificers, and manufacturers, can grow rich only through parsimony and privation. As the interest of nations so differently circumstanced is very different, so is likewise the common character of the people. In those of the former kind, liberality, frankness, and good fellowship, naturally make a part of their common character; in the latter, narrowness, meanness, and a selfish disposition, averse to all social pleasure and enjoyment.

The unproductive class, that of merchants, artificers, and manufacturers, is maintained and employed altogether at the expense of the two other classes, of that of proprietors, and of that of cultivators. They furnish it both with the materials of its work, and with the fund of its subsistence, with the corn and cattle which it consumes while it is employed about that work. The proprietors and cultivators finally pay both the wages of all the workmen of the unproductive class, and the profits of all their employers. Those workmen and their employers are properly the servants of the proprietors and cultivators. They are only servants who work without doors, as menial servants work within. Both the one and the other, however, are equally maintained at the expense of the same masters. The labour of both is equally unproductive. It adds nothing to the value of the sum total of the rude produce of the land. Instead of increasing the value of that sum total, it is a charge and expense which must be paid out of it.

The unproductive class, however, is not only useful, but greatly useful, to the other two classes. By means of the industry of merchants, artificers, and manufacturers, the proprietors and cultivators can purchase both the foreign goods and the manufactured produce of their own country, which they have occasion for, with the produce of a much smaller quantity of their own labour, than what they would be obliged to employ, if they were to attempt, in an awkward and unskilful manner, either to import the one, or to make the other, for their own use. By means of the unproductive class, the cultivators are delivered from many cares, which would otherwise distract their attention from the cultivation of land. The superiority of produce, which in consequence of this undivided attention, they are enabled to raise, is fully sufficient to pay the whole expense which the maintenance and employment of the unproductive class costs either the proprietors or themselves. The industry of merchants, artificers, and manufacturers, though in its own nature altogether unproductive, yet contributes in this manner indirectly to increase the produce of the land. It increases the productive powers of productive labour, by leaving it at liberty to confine itself to its proper employment, the cultivation of land; and the plough goes frequently the easier and the better, by means of the labour of the man whose business is most remote from the plough.

It can never be the interest of the proprietors and cultivators, to restrain or to discourage, in any respect, the industry of merchants, artificers, and manufacturers. The greater the liberty which this unproductive class enjoys, the greater will be the competition in all the different trades which compose it, and the cheaper will the other two classes be supplied, both with foreign goods and with the manufactured produce of their own country.

It can never be the interest of the unproductive class to oppress the other two classes. It is the surplus produce of the land, or what remains after deducting the maintenance, first of the cultivators, and afterwards of the proprietors, that maintains and employs the unproductive class. The greater this surplus, the greater must likewise be the maintenance and employment of that class. The establishment of perfect justice, of perfect liberty, and of perfect equality, is the very simple secret which most effectually secures the highest degree of prosperity to all the three classes.

The merchants, artificers, and manufacturers of those mercantile states, which, like Holland and Hamburgh, consist chiefly of this unproductive class, are in the same manner maintained and employed altogether at the expense of the proprietors and cultivators of land. The only difference is, that those proprietors and cultivators are, the greater part of them, placed at a most inconvenient distance from the merchants, artificers, and manufacturers, whom they supply with the materials of their work and the fund of their subsistence; are the inhabitants of other countries, and the subjects of other governments.

Such mercantile states, however, are not only useful, but greatly useful, to the inhabitants of those other countries. They fill up, in some measure, a very important void; and supply the place of the merchants, artificers, and manufacturers, whom the inhabitants of those countries ought to find at home, but whom, from some defect in their policy, they do not find at home.

It can never be the interest of those landed nations, if I may call them so, to discourage or distress the industry of such mercantile states, by imposing high duties upon their trade, or upon the commodities which they furnish. Such duties, by rendering those commodities dearer, could serve only to sink the real value of the surplus produce of their own land, with which, or, what comes to the same thing, with the price of which those commodities are purchased. Such duties could only serve to discourage the increase of that surplus produce, and consequently the improvement and cultivation of their own land. The most effectual expedient, on the contrary, for raising the value of that surplus produce, for encouraging its increase, and consequently the improvement and cultivation of their own land, would be to allow the most perfect freedom to the trade of all such mercantile nations.

This perfect freedom of trade would even be the most effectual expedient for supplying them, in due time, with all the artificers, manufacturers, and merchants, whom they wanted at home; and for filling up, in the properest and most advantageous manner, that very important void which they felt there.
