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

by Adam Smith

The order of proprietors may perhaps gain more by the prosperity of the society than that of labourers; but there is no order that suffers so cruelly from its decline. But though the interest of the labourer is strictly connected with that of the society, he is incapable either of comprehending that interest, or of understanding its connexion with his own. His condition leaves him no time to receive the necessary information, and his education and habits are commonly such as to render him unfit to judge, even though he was fully informed. In the public deliberations, therefore, his voice is little heard, and less r...

As during their whole lives they are engaged in plans and projects, they have frequently more acuteness of understanding than the greater part of country gentlemen. As their thoughts, however, are commonly exercised rather about the interest of their own particular branch of business. than about that of the society, their judgment, even when given with the greatest candour (which it has not been upon every occasion), is much more to be depended upon with regard to the former of those two objects, than with regard to the latter.

In that rude state of society, in which there is no division of labour, in which exchanges are seldom made, and in which every man provides every thing for himself, it is not necessary that any stock should be accumulated, or stored up before-hand, in order to carry on the business of the society. Every man endeavours to supply, by his own industry, his own occasional wants, as they occur. When he is hungry, he goes to the forest to hunt; when his coat is worn out, he clothes himself with the skin of the first large animal he kills: and when his hut begins to go to ruin, he repairs it, as well as he can, with the trees and the turf that are nearest it.

But when the division of labour has once been thoroughly introduced, the produce of a man's own labour can supply but a very small part of his occasional wants.

The far greater part of them are supplied by the produce of other men's labour, which he purchases with the produce, or, what is the same thing, with the price of the produce, of his own. But this purchase cannot be made till such time as the...

In the following book, I have endeavoured to explain the nature of stock, the effects of its accumulation into capital of different kinds, and the effects of the different employments of those capitals.

There are two different ways in which a capital may be employed so as to yield a revenue or profit to its employer. First, it maybe employed in raising, manufacturing, or purchasing goods, and selling them again with a profit. The capital employed in this manner yields no revenue or profit to its employer, while it either remains in his possession, or continues in the same shape. The goods of the merchant yield him no revenue or profit till he sells them for money, and the money yields him as little till it is again exchanged for goods. His capital is continually going from him in one shape, and returning to him in another; and it is only by means of such circulation, or successive changes, that it can yield him any profit. Such capitals, therefore, may very properly be called circulating capitals. Secondly, it may be employed in the improvement of land, in the purchase of useful machines and instruments of trade, or in such like things as yield a revenue or profit without changing masters, or circulating any further. Such capitals, therefore, may very properly be called fixed capitals.

The third and last of the three portions into which the general stock of the society naturally divides itself, is the circulating capital, of which the characteristic is, that it affords a revenue only by circulating or changing masters. It is composed likewise of four parts.

First, of the money, by means of which all the other three are circulated and distributed to their proper consumers. Secondly, of the stock of provisions which are in the possession of the butcher, the grazier, the farmer, the corn-merchant, the brewer, etc. and from the sale of which they expect to derive a profit. Thirdly, of the materials, whether altogether rude, or more or less manufactured, of clothes, furniture, and building which are not yet made up into any of those three shapes, but which remain in the hands of the growers, the manufacturers, the mercers, and drapers, the timber-merchants, the carpenters and joiners, the brick-makers, etc. Fourthly, and lastly, of the work which is made up and completed, but which is still in the hands of the merchant and manufacturer, and not yet disposed of or distributed to the proper consumers; such as the finished work

The circulating capital consists, in this manner, of the provisions, materials, and finished work of all kinds that are in the hands of their respective dealers, and of the money that is necessary for circulating and distributing them to those who are finally to use or to consume them.

Every fixed capital is both originally derived from, and requires to be continually supported by, a circulating capital. All useful machines and instruments of trade are originally derived from a circulating capital, which furnishes the materials of which they are made, and the maintenance of the workmen who make them. They require, too, a capital of the same kind to keep them in constant repair.

That revenue, therefore, cannot consist in those metal pieces, of which the amount is so much inferior to its value, but in the power of purchasing, in the goods which can successively be bought with them as they circulate from hand to hand.

Money, therefore, the great wheel of circulation, the great instrument of commerce, like all other instruments of trade, though it makes a part, and a very valuable part, of the capital, makes no part of the revenue of the society to which it belongs; and though the metal pieces of which it is composed, in the course of their annual circulation, distribute to every man the revenue which properly belongs to him, they make themselves no part of that revenue.

In the present times, the whole circulation of Scotland cannot be estimated at less than two millions, of which that part which consists in gold and silver, most probably, does not amount to half a million.

By issuing too great a quantity of paper, of which the excess was continually returning, in order to be exchanged for gold and silver, the Bank of England was for many years together obliged to coin gold to the extent of between eight hundred thousand pounds and a million a-year; or, at an average, about eight hundred and fifty thousand pounds.

If the paper money which the bank advances never exceeds this value, it can never exceed the value of the gold and silver which would necessarily circulate in the country if there was no paper money; it can never exceed the quantity which the circulation of the country can easily absorb and employ.

The returns of the fixed capital are, in almost all cases, much slower than those of the circulating capital: and such expenses, even when laid out with the greatest prudence and judgment, very seldom return to the undertaker till after a period of many years, a period by far too distant to suit the conveniency of a bank.

But those bank notes being, the greater part of them, over and above what the circulation of the country could easily absorb and employ, returned upon it, in order to be exchanged for gold and silver, as fast as they were issued.

The stability of the bank of England is equal to that of the British government. All that it has advanced to the public must be lost before its creditors can sustain any loss. No other banking company in England can be established by act of parliament, or can consist of more than six members. It acts, not only as an ordinary bank, but as a great engine of state. It receives and pays the greater part of the annuities which are due to the creditors of the public; it circulates exchequer bills; and it advances to government the annual amount of the land and malt taxes, which are frequently not paid up till some years thereafter. In these different operations, its duty to the public may sometimes have obliged it, without any fault of its directors, to overstock the circulation with paper money.

The gold and silver money which circulates in any country may very properly be compared to a highway, which, while it circulates and carries to market all the grass and corn of the country, produces itself not a single pile of either. The judicious operations of banking, by providing, if I may be allowed so violent a metaphor, a sort of waggon-way through the air, enable the country to convert, as it were, a great part of its highways into good pastures, and corn fields, and thereby to increase, very considerably, the annual produce of its land and labour.

No law, therefore, could be more equitable than the act of parliament, so unjustly complained of in the colonies, which declared, that no paper currency to be emitted there in time coming, should be a legal tender of payment.

The late multiplication of banking companies in both parts of the united kingdom, an event by which many people have been much alarmed, instead of diminishing, increases the security of the public. It obliges all of them to be more circumspect in their conduct, and, by not extending their currency beyond its due proportion to their cash, to guard themselves against those malicious runs, which the rivalship of so many competitors is always ready to bring upon them.

The labour of the menial servant, on the contrary, does not fix or realize itself in any particular subject or vendible commodity. His services generally perish in the very instant of their performance, and seldom leave any trace of value behind them, for which an equal quantity of service could afterwards be procured.

Though the whole annual produce of the land and labour of every country is no doubt ultimately destined for supplying the consumption of its inhabitants, and for procuring a revenue to them; yet when it first comes either from the ground, or from the hands of the productive labourers, it naturally divides itself into two parts. One of them, and frequently the largest, is, in the first place, destined for replacing a capital, or for renewing the provisions, materials, and finished work, which had been withdrawn from a capital; the other for constituting a revenue either to the owner of this capital, as the profit of his stock, or to some other person, as the rent of his land.

The proportion, therefore, between the productive and unproductive hands, depends very much in every country upon the proportion between that part of the annual produce, which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined for replacing a capital, and that which is destined for constituting a revenue, either as rent or as profit. This proportion is very different in rich from what it is in poor countries.

In the midst of all the exactions of government, this capital has been silently and gradually accumulated by the private frugality and good conduct of individuals, by their universal, continual, and uninterrupted effort to better their own condition. It is this effort, protected by law, and allowed by liberty to exert itself in the manner that is most advantageous, which has maintained the progress of England towards opulence and improvement in almost all former times, and which, it is to be hoped, will do so in all future times.

In some countries the interest of money has been prohibited by law. But as something can everywhere be made by the use of money, something ought everywhere to be paid for the use of it. This regulation, instead of preventing, has been found from experience to increase the evil of usury. The debtor being obliged to pay, not only for the use of the money, but for the risk which his creditor runs by accepting a compensation for that use, he is obliged, if one may say so, to insure his creditor from the penalties of usury.

In countries where interest is permitted, the law in order to prevent the extortion of usury, generally fixes the highest rate which can be taken without incurring a penalty.

The legal rate, it is to be observed, though it ought to be somewhat above, ought not to be much above the lowest market rate. If the legal rate of interest in Great Britain, for example, was fixed so high as eight or ten per cent. the greater part of the money which was to be lent, would be lent to prodigals and projectors, who alone would be willing to give this high interest.

Sober people, who will give for the use of money no more than a part of what they are likely to make by the use of it, would not venture into the competition. A great part of the capital of the country would thus be kept out of the hands which were most likely to make a profitable and advantageous use of it, and thrown into those which were most likely to waste and destroy it.

A particular country, in the same manner as a particular person, may frequently not have capital sufficient both to improve and cultivate all its lands, to manufacture and prepare their whole rude produce for immediate use and consumption, and to transport the surplus part either of the rude or manufactured produce to those distant markets, where it can be exchanged for something for which there is a demand at home. The inhabitants of many different parts of Great Britain have not capital sufficient to improve and cultivate all their lands.

Were the Americans, either by combination, or by any other sort of violence, to stop the importation of European manufactures, and, by thus giving a monopoly to such of their own countrymen as could manufacture the like goods, divert any considerable part of their capital into this employment, they would retard, instead of accelerating, the further increase in the value of their annual produce, and would obstruct, instead of promoting, the progress of their country towards real wealth and greatness.

It is not for its own sake that men desire money, but for the sake of what they can purchase with it.

What is prudence in the conduct of every private family, can scarce be folly in that of a great kingdom.

If a foreign country can supply us with a commodity cheaper than we ourselves can make it, better buy it of them with some part of the produce of our own industry, employed in a way in which we have some advantage.

The case in which it may sometimes be a matter of deliberation how far it is proper to continue the free importation of certain foreign goods, is when some foreign nation restrains, by high duties or prohibitions, the importation of some of our manufactures into their country. Revenge, in this case, naturally dictates retaliation, and that we should impose the like duties and prohibitions upon the importation of some or all of their manufactures into ours. Nations, accordingly, seldom fail to retaliate in this manner.

There may be good policy in retaliations of this kind, when there is a probability that they will procure the repeal of the high duties or prohibitions complained of. The recovery of a great foreign market will generally more than compensate the transitory inconveniency of paying dearer during a short time for some sorts of goods. To judge whether such retaliations are likely to produce such an effect, does not, perhaps, belong so much to the science of a legislator, whose deliberations ought to be governed by general principles, which are always the same, as to the skill of that insidious and crafty animal vulgarly called a statesman or politician, whose councils are directed by the momentary fluctuations of affairs.

To expect, indeed, that the freedom of trade should ever be entirely restored in Great Britain, is as absurd as to expect that an Oceana or Utopia should ever be established in it. Not only the prejudices of the public, but, what is much more unconquerable, the private interests of many individuals, irresistibly oppose it. Were the officers of the army to oppose, with the same zeal and unanimity, any reduction in the number of forces, with which master manufacturers set themselves against every law that is likely to increase the number of their rivals in the home market; were the former to animate their soldiers. In the same manner as the latter inflame their workmen, to attack with violence and outrage the proposers of any such regulation; to attempt to reduce the army would be as dangerous as it has now become to attempt to diminish, in any respect, the monopoly which our manufacturers have obtained against us.

Every such regulation introduces some degree of real disorder into the constitution of the state, which it will be difficult afterwards to cure without occasioning another disorder.

Taxes imposed with a view to prevent, or even to diminish importation, are evidently as destructive of the revenue of the customs as of the freedom of trade.

To lay extraordinary restraints upon the importation of goods of almost all kinds, from those particular countries with which the balance of trade is supposed to be disadvantageous, is the second expedient by which the commercial system proposes to increase the quantity of gold and silver.

The French, in their turn, have, I believe, treated our goods and manufactures just as hardly; though I am not so well acquainted with the particular hardships which they have imposed upon them. Those mutual restraints have put an end to almost all fair commerce between the two nations; and smugglers are now the principal importers, either of British goods into France, or of French goods into Great Britain.

Nothing, however, can be more absurd than this whole doctrine of the balance of trade, upon which, not only these restraints, but almost all the other regulations of commerce, are founded. When two places trade with one another, this doctrine supposes that, if the balance be even, neither of them either loses or gains; but if it leans in any degree to one side, that one of them loses, and the other gains, in proportion to its declension from the exact equilibrium. Both suppositions are false. A trade, which is forced by means of bounties and monopolies, may be, and commonly is, disadvantageous to the country in whose favour it is meant to be established, as I shall endeavour to show hereafter. But that trade which, without force or constraint, is naturally and regularly carried on between any two places, is always advantageous, though not always equally so, to both.

By such maxims as these, however, nations have been taught that their interest consisted in beggaring all their neighbours. Each nation has been made to look with an invidious eye upon the prosperity of all the nations with which it trades, and to consider their gain as its own loss. Commerce, which ought naturally to be, among nations as among individuals, a bond of union and friendship, has become the most fertile source of discord and animosity.

The violence and injustice of the rulers of mankind is an ancient evil, for which, I am afraid, the nature of human affairs can scarce admit of a remedy: but the mean rapacity, the monopolizing spirit, of merchants and manufacturers, who neither are, nor ought to be, the rulers of mankind, though it cannot, perhaps, be corrected, may very easily be prevented from disturbing the tranquillity of anybody but themselves.

Private people, who want to make a fortune, never think of retiring to the remote and poor provinces of the country, but resort either to the capital, or to some of the great commercial towns. They know, that where little wealth circulates, there is little to be got; but that where a great deal is in motion, some share of it may fall to them.

If the exchangeable value of the annual produce, it has already been observed, exceeds that of the annual consumption, the capital of the society must annually increase in proportion to this excess. The society in this case lives within its revenue; and what is annually saved out of its revenue, is naturally added to its capital, and employed so as to increase still further the annual produce.

If the exchangeable value of the annual produce, on the contrary, fall short of the annual consumption, the capital of the society must annually decay in proportion to this deficiency.

The expense of the society, in this case, exceeds its revenue, and necessarily encroaches upon its capital. Its capital, therefore, must necessarily decay, and, together with it, the exchan...

This balance of produce and consumption is entirely different from what is called the balance of trade. It might take place in a nation which had no foreign trade, but which was entirely separated from all the world. It may take place in the whole globe of the earth, of which the wealth, populati...
