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

The continual increase of the surplus produce of their land would, in due time, create a greater capital than what would be employed with the ordinary rate of profit in the improvement and cultivation of land; and the surplus part of it would naturally turn itself to the employment of artificers and manufacturers, at home. But these artificers and manufacturers, finding at home both the materials of their work and the fund of their subsistence, might immediately, even with much less art and skill be able to work as cheap as the little artificers and manufacturers of such mercantile states, who had both to bring from a greater distance. Even though, from want of art and skill, they might not for some time be able to work as cheap, yet, finding a market at home, they might be able to sell their work there as cheap as that of the artificers and manufacturers of such mercantile states, which could not be brought to that market but from so great a distance; and as their art and skill improved, they would soon be able to sell it cheaper. The artificers and manufacturers of such mercantile states, therefore, would immediately be rivalled in the market of those landed nations, and soon after undersold and justled out of it altogether. The cheapness of the manufactures of those landed nations, in consequence of the gradual improvements of art and skill, would, in due time, extend their sale beyond the home market, and carry them to many foreign markets, from which they would, in the same manner, gradually justle out many of the manufacturers of such mercantile nations.

This continual increase, both of the rude and manufactured produce of those landed nations, would, in due time, create a greater capital than could, with the ordinary rate of profit, be employed either in agriculture or in manufactures. The surplus of this capital would naturally turn itself to foreign trade, and be employed in exporting, to foreign countries, such parts of the rude and manufactured produce of its own country, as exceeded the demand of the home market. In the exportation of the produce of their own country, the merchants of a landed nation would have an advantage of the same kind over those of mercantile nations, which its artificers and manufacturers had over the artificers and manufacturers of such nations; the advantage of finding at home that cargo, and those stores and provisions, which the others were obliged to seek for at a distance. With inferior art and skill in navigation, therefore, they would be able to sell that cargo as cheap in foreign markets as the merchants of such mercantile nations; and with equal art and skill they would be able to sell it cheaper. They would soon, therefore, rival those mercantile nations in this branch of foreign trade, and, in due time, would justle them out of it altogether.

According to this liberal and generous system, therefore, the most advantageous method in which a landed nation can raise up artificers, manufacturers, and merchants of its own, is to grant the most perfect freedom of trade to the artificers, manufacturers, and merchants of all other nations. It thereby raises the value of the surplus produce of its own land, of which the continual increase gradually establishes a fund, which, in due time, necessarily raises up all the artificers, manufacturers, and merchants, whom it has occasion for.

When a landed nation on the contrary, oppresses, either by high duties or by prohibitions, the trade of foreign nations, it necessarily hurts its own interest in two different ways. First, by raising the price of all foreign goods, and of all sorts of manufactures, it necessarily sinks the real value of the surplus produce of its own land, with which, or, what comes to the same thing, with the price of which, it purchases those foreign goods and manufactures. Secondly, by giving a sort of monopoly of the home market to its own merchants, artificers, and manufacturers, it raises the rate of mercantile and manufacturing profit, in proportion to that of agricultural profit; and, consequently, either draws from agriculture a part of the capital which had before been employed in it, or hinders from going to it a part of what would otherwise have gone to it. This policy, therefore, discourages agriculture in two different ways; first, by sinking the real value of its produce, and thereby lowering the rate of its profits; and, secondly, by raising the rate of profit in all other employments. Agriculture is rendered less advantageous, and trade and manufactures more advantageous, than they otherwise would be; and every man is tempted by his own interest to turn, as much as he can, both his capital and his industry from the former to the latter employments.

Though, by this oppressive policy, a landed nation should be able to raise up artificers, manufacturers, and merchants of its own, somewhat sooner than it could do by the freedom of trade; a matter, however, which is not a little doubtful; yet it would raise them up, if one may say so, prematurely, and before it was perfectly ripe for them. By raising up too hastily one species of industry, it would depress another more valuable species of industry. By raising up too hastily a species of industry which only replaces the stock which employs it, together with the ordinary profit, it would depress a species of industry which, over and above replacing that stock, with its profit, affords likewise a neat produce, a free rent to the landlord. It would depress productive labour, by encouraging too hastily that labour which is altogether barren and unproductive.

In what manner, according to this system, the sum total of the annual produce of the land is distributed among the three classes above mentioned, and in what manner the labour of the unproductive class does no more than replace the value of its own consumption, without increasing in any respect the value of that sum total, is represented by Mr Quesnai, the very ingenious and profound author of this system, in some arithmetical formularies. The first of these formularies, which, by way of eminence, he peculiarly distinguishes by the name of the Economical Table, represents the manner in which he supposes this distribution takes place, in a state of the most perfect liberty, and, therefore, of the highest prosperity; in a state where the annual produce is such as to afford the greatest possible neat produce, and where each class enjoys its proper share of the whole annual produce. Some subsequent formularies represent the manner in which he supposes this distribution is made in different states of restraint and regulation; in which, either the class of proprietors, or the barren and unproductive class, is more favoured than the class of cultivators; and in which either the one or the other encroaches, more or less, upon the share which ought properly to belong to this productive class. Every such encroachment, every violation of that natural distribution, which the most perfect liberty would establish, must, according to this system, necessarily degrade, more or less, from one year to another, the value and sum total of the annual produce, and must necessarily occasion a gradual declension in the real wealth and revenue of the society; a declension, of which the progress must be quicker or slower, according to the degree of this encroachment, according as that natural distribution, which the most perfect liberty would establish, is more or less violated. Those subsequent formularies represent the different degrees of declension which, according to this system, correspond to the different degrees in which this natural distribution of things is violated.

Some speculative physicians seem to have imagined that the health of the human body could be preserved only by a certain precise regimen of diet and exercise, of which every, the smallest violation, necessarily occasioned some degree of disease or disorder proportionate to the degree of the violation. Experience, however, would seem to shew, that the human body frequently preserves, to all appearance at least, the most perfect state of health under a vast variety of different regimens; even under some which are generally believed to be very far from being perfectly wholesome. But the healthful state of the human body, it would seem, contains in itself some unknown principle of preservation, capable either of preventing or of correcting, in many respects, the bad effects even of a very faulty regimen. Mr Quesnai, who was himself a physician, and a very speculative physician, seems to have entertained a notion of the same kind concerning the political body, and to have imagined that it would thrive and prosper only under a certain precise regimen, the exact regimen of perfect liberty and perfect justice. He seems not to have considered, that in the political body, the natural effort which every man is continually making to better his own condition, is a principle of preservation capable of preventing and correcting, in many respects, the bad effects of a political economy, in some degree both partial and oppressive. Such a political economy, though it no doubt retards more or less, is not always capable of stopping altogether, the natural progress of a nation towards wealth and prosperity, and still less of making it go backwards. If a nation could not prosper without the enjoyment of perfect liberty and perfect justice, there is not in the world a nation which could ever have prospered. In the political body, however, the wisdom of nature has fortunately made ample provision for remedying many of the bad effects of the folly and injustice of man; in the same manner as it has done in the natural body, for remedying those of his sloth and intemperance.

The capital error of this system, however, seems to lie in its representing the class of artificers, manufacturers, and merchants, as altogether barren and unproductive. The following observations may serve to shew the impropriety of this representation: —

First, this class, it is acknowledged, reproduces annually the value of its own annual consumption, and continues, at least, the existence of the stock or capital which maintains and employs it. But, upon this account alone, the denomination of barren or unproductive should seem to be very improperly applied to it. We should not call a marriage barren or unproductive, though it produced only a son and a daughter, to replace the father and mother, and though it did not increase the number of the human species, but only continued it as it was before. Farmers and country labourers, indeed, over and above the stock which maintains and employs them, reproduce annually a neat produce, a free rent to the landlord. As a marriage which affords three children is certainly more productive than one which affords only two, so the labour of farmers and country labourers is certainly more productive than that of merchants, artificers, and manufacturers. The superior produce of the one class, however, does not, render the other barren or unproductive.

Secondly, it seems, on this account, altogether improper to consider artificers, manufacturers, and merchants, in the same light as menial servants. The labour of menial servants does not continue the existence of the fund which maintains and employs them. Their maintenance and employment is altogether at the expense of their masters, and the work which they perform is not of a nature to repay that expense. That work consists in services which perish generally in the very instant of their performance, and does not fix or realize itself in any vendible commodity, which can replace the value of their wages and maintenance. The labour, on the contrary, of artificers, manufacturers, and merchants, naturally does fix and realize itself in some such vendible commodity. It is upon this account that, in the chapter in which I treat of productive and unproductive labour, I have classed artificers, manufacturers, and merchants among the productive labourers, and menial servants among the barren or unproductive.

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 to 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 necessaries 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 depends, 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 improvement in a much higher degree.42 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.

Fifthly and lastly, though the revenue of the inhabitants of every country was supposed to consist altogether, as this system seems to suppose, in the quantity of subsistence which their industry could procure to them; yet, even upon this supposition, the revenue of a trading and manufacturing country must, other things being equal, always be much greater than that of one without trade or manufactures. By means of trade and manufactures, a greater quantity of subsistence can be annually imported into a particular country, than what its own lands, in the actual state of their cultivation, could afford. The inhabitants of a town, though they frequently possess no lands of their own, yet draw to themselves, by their industry, such a quantity of the rude produce of the lands of other people, as supplies them, not only with the materials of their work, but with the fund of their subsistence. What a town always is with regard to the country in its neighbourhood, one independent state or country may frequently be with regard to other independent states or countries. It is thus that Holland draws a great part of its subsistence from other countries; live cattle from Holstein and Jutland, and corn from almost all the different countries of Europe. A small quantity of manufactured produce, purchases a great quantity of rude produce. A trading and manufacturing country, therefore, naturally purchases, with a small part of its manufactured produce, a great part of the rude produce of other countries; while, on the contrary, a country without trade and manufactures is generally obliged to purchase, at the expense of a great part of its rude produce, a very small part of the manufactured produce of other countries. The one exports what can subsist and accommodate but a very few, and imports the subsistence and accommodation of a great number. The other exports the accommodation and subsistence of a great number, and imports that of a very few only. The inhabitants of the one must always enjoy a much greater quantity of subsistence than what their own lands, in the actual state of their cultivation, could afford. The inhabitants of the other most always enjoy a much smaller quantity.

This system, however, with all its imperfections, is perhaps the nearest approximation to the truth that has yet been published upon the subject of political economy; and is upon that account, well worth the consideration of every man who wishes to examine with attention the principles of that very important science. Though in representing the labour which is employed upon land as the only productive labour, the notions which it inculcates are, perhaps, too narrow and confined; yet in representing the wealth of nations as consisting, not in the unconsumable riches of money, but in the consumable goods annually reproduced by the labour of the society, and in representing perfect liberty as the only effectual expedient for rendering this annual reproduction the greatest possible, its doctrine seems to be in every respect as just as it is generous and liberal. Its followers are very numerous; and as men are fond of paradoxes, and of appearing to understand what surpasses the comprehensions of ordinary people, the paradox which it maintains, concerning the unproductive nature of manufacturing labour, has not, perhaps, contributed a little to increase the number of its admirers. They have for some years past made a pretty considerable sect, distinguished in the French republic of letters by the name of the Economists. Their works have certainly been of some service to their country; not only by bringing into general discussion, many subjects which had never been well examined before, but by influencing, in some measure, the public administration in favour of agriculture. It has been in consequence of their representations, accordingly, that the agriculture of France has been delivered from several of the oppressions which it before laboured under. The term, during which such a lease can be granted, as will be valid against every future purchaser or proprietor of the land, has been prolonged from nine to twenty-seven years. The ancient provincial restraints upon the transportation of corn from one province of the kingdom to another, have been entirely taken away; and the liberty of exporting it to all foreign countries, has been established as the common law of the kingdom in all ordinary cases. This sect, in their works, which are very numerous, and which treat not only of what is properly called Political Economy, or of the nature and causes of the wealth of nations, but of every other branch of the system of civil government, all follow implicitly, and without any sensible variation, the doctrine of Mr. Quesnai. There is, upon this account, little variety in the greater part of their works. The most distinct and best connected account of this doctrine is to be found in a little book written by Mr. Mercier de la Riviere, some time intendant of Martinico, entitled, The natural and essential Order of Political Societies. The admiration of this whole sect for their master, who was himself a man of the greatest modesty and simplicity, is not inferior to that of any of the ancient philosophers for the founders of their respective systems. 'There have been since the world began,' says a very diligent and respectable author, the Marquis de Mirabeau, 'three great inventions which have principally given stability to political societies, independent of many other inventions which have enriched and adorned them. The first is the invention of writing, which alone gives human nature the power of transmitting, without alteration, its laws, its contracts, its annals, and its discoveries. The second is the invention of money, which binds together all the relations between civilized societies. The third is the economical table, the result of the other two, which completes them both by perfecting their object; the great discovery of our age, but of which our posterity will reap the benefit.'

As the political economy of the nations of modern Europe has been more favourable to manufactures and foreign trade, the industry of the towns, than to agriculture, the industry of the country; so that of other nations has followed a different plan, and has been more favourable to agriculture than to manufactures and foreign trade.

The policy of China favours agriculture more than all other employments. In China, the condition of a labourer is said to be as much superior to that of an artificer, as in most parts of Europe that of an artificer is to that of a labourer. In China, the great ambition of every man is to get possession of a little bit of land, either in property or in lease; and leases are there said to be granted upon very moderate terms, and to be sufficiently secured to the lessees. The Chinese have little respect for foreign trade. Your beggarly commerce! was the language in which the mandarins of Pekin used to talk to Mr. De Lange, the Russian envoy, concerning it43. Except with Japan, the Chinese carry on, themselves, and in their own bottoms, little or no foreign trade; and it is only into one or two ports of their kingdom that they even admit the ships of foreign nations. Foreign trade, therefore, is, in China, every way confined within a much narrower circle than that to which it would naturally extend itself, if more freedom was allowed to it, either in their own ships, or in those of foreign nations.

Manufactures, as in a small bulk they frequently contain a great value, and can upon that account be transported at less expense from one country to another than most parts of rude produce, are, in almost all countries, the principal support of foreign trade. In countries, besides, less extensive, and less favourably circumstanced for inferior commerce than China, they generally require the support of foreign trade. Without an extensive foreign market, they could not well flourish, either in countries so moderately extensive as to afford but a narrow home market, or in countries where the communication between one province and another was so difficult, as to render it impossible for the goods of any particular place to enjoy the whole of that home market which the country could afford. The perfection of manufacturing industry, it must be remembered, depends altogether upon the division of labour; and the degree to which the division of labour can be introduced into any manufacture, is necessarily regulated, it has already been shewn, by the extent of the market. But the great extent of the empire of China, the vast multitude of its inhabitants, the variety of climate, and consequently of productions in its different provinces, and the easy communication by means of water-carriage between the greater part of them, render the home market of that country of so great extent, as to be alone sufficient to support very great manufactures, and to admit of very considerable subdivisions of labour. The home market of China is, perhaps, in extent, not much inferior to the market of all the different countries of Europe put together. A more extensive foreign trade, however, which to this great home market added the foreign market of all the rest of the world, especially if any considerable part of this trade was carried on in Chinese ships, could scarce fail to increase very much the manufactures of China, and to improve very much the productive powers of its manufacturing industry. By a more extensive navigation, the Chinese would naturally learn the art of using and constructing, themselves, all the different machines made use of in other countries, as well as the other improvements of art and industry which are practised in all the different parts of the world. Upon their present plan, they have little opportunity of improving themselves by the example of any other nation, except that of the Japanese.
