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

by Adam Smith

In the opulent countries of Europe, great capitals are at present employed in trade and manufactures. In the ancient state, the little trade that was stirring, and the few homely and coarse manufactures that were carried on, required but very small capitals. These, however, must have yielded very large profits. The rate of interest was nowhere less than ten per cent. and their profits must have been sufficient to afford this great interest. At present, the rate of interest, in the improved parts of Europe, is nowhere higher than six per cent.; and in some of the most improved, it is so low as four, three, and two per cent. Though that part of the revenue of the inhabitants which is derived from the profits of stock, is always much greater in rich than in poor countries, it is because the stock is much greater; in proportion to the stock, the profits are generally much less.

That part of the annual produce, therefore, which, as soon as it comes either from the ground, or from the hands of the productive labourers, is destined for replacing a capital, is not only much greater in rich than in poor countries, but bears a much greater proportion to that which is immediately destined for constituting a revenue either as rent or as profit. The funds destined for the maintenance of productive labour are not only much greater in the former than in the latter, but bear a much greater proportion to those which, though they may be employed to maintain either productive or unproductive hands, have generally a predilection for the latter.

The proportion between those different funds necessarily determines in every country the general character of the inhabitants as to industry or idleness. We are more industrious than our forefathers, because, in the present times, the funds destined for the maintenance of industry are much greater in proportion to those which are likely to be employed in the maintenance of idleness, than they were two or three centuries ago. Our ancestors were idle for want of a sufficient encouragement to industry. It is better, says the proverb, to play for nothing, than to work for nothing. In mercantile and manufacturing towns, where the inferior ranks of people are chiefly maintained by the employment of capital, they are in general industrious, sober, and thriving; as in many English, and in most Dutch towns. In those towns which are principally supported by the constant or occasional residence of a court, and in which the inferior ranks of people are chiefly maintained by the spending of revenue, they are in general idle, dissolute, and poor; as at Rome, Versailles, Compeigne, and Fontainbleau. If you except Rouen and Bourdeaux, there is little trade or industry in any of the parliament towns of France; and the inferior ranks of people, being chiefly maintained by the expense of the members of the courts of justice, and of those who come to plead before them, are in general idle and poor. The great trade of Rouen and Bourdeaux seems to be altogether the effect of their situation. Rouen is necessarily the entrepot of almost all the goods which are brought either from foreign countries, or from the maritime provinces of France, for the consumption of the great city of Paris. Bourdeaux is, in the same manner, the entrepot of the wines which grow upon the banks of the Garronne, and of the rivers which run into it, one of the richest wine countries in the world, and which seems to produce the wine fittest for exportation, or best suited to the taste of foreign nations. Such advantageous situations necessarily attract a great capital by the great employment which they afford it; and the employment of this capital is the cause of the industry of those two cities. In the other parliament towns of France, very little more capital seems to be employed than what is necessary for supplying their own consumption; that is, little more than the smallest capital which can be employed in them. The same thing may be said of Paris, Madrid, and Vienna. Of those three cities, Paris is by far the most industrious, but Paris itself is the principal market of all the manufactures established at Paris, and its own consumption is the principal object of all the trade which it carries on. London, Lisbon, and Copenhagen, are, perhaps, the only three cities in Europe, which are both the constant residence of a court, and can at the same time be considered as trading cities, or as cities which trade not only for their own consumption, but for that of other cities and countries. The situation of all the three is extremely advantageous, and naturally fits them to be the entrepots of a great part of the goods destined for the consumption of distant places. In a city where a great revenue is spent, to employ with advantage a capital for any other purpose than for supplying the consumption of that city, is probably more difficult than in one in which the inferior ranks of people have no other maintenance but what they derive from the employment of such a capital. The idleness of the greater part of the people who are maintained by the expense of revenue, corrupts, it is probable, the industry of those who ought to be maintained by the employment of capital, and renders it less advantageous to employ a capital there than in other places. There was little trade or industry in Edinburgh before the Union. When the Scotch parliament was no longer to be assembled in it, when it ceased to be the necessary residence of the principal nobility and gentry of Scotland, it became a city of some trade and industry. It still continues, however, to be the residence of the principal courts of justice in Scotland, of the boards of customs and excise, etc. A considerable revenue, therefore, still continues to be spent in it. In trade and industry, it is much inferior to Glasgow, of which the inhabitants are chiefly maintained by the employment of capital. The inhabitants of a large village, it has sometimes been observed, after having made considerable progress in manufactures, have become idle and poor, in consequence of a great lord’s having taken up his residence in their neighbourhood.

The proportion between capital and revenue, therefore, seems everywhere to regulate the proportion between industry and idleness Wherever capital predominates, industry prevails; wherever revenue, idleness. Every increase or diminution of capital, therefore, naturally tends to increase or diminish the real quantity of industry, the number of productive hands, and consequently the exchangeable value of the annual produce of the land and labour of the country, the real wealth and revenue of all its inhabitants.

Capitals are increased by parsimony, and diminished by prodigality and misconduct.

Whatever a person saves from his revenue he adds to his capital, and either employs it himself in maintaining an additional number of productive hands, or enables some other person to do so, by lending it to him for an interest, that is, for a share of the profits. As the capital of an individual can be increased only by what he saves from his annual revenue or his annual gains, so the capital of a society, which is the same with that of all the individuals who compose it, can be increased only in the same manner.

Parsimony, and not industry, is the immediate cause of the increase of capital. Industry, indeed, provides the subject which parsimony accumulates; but whatever industry might acquire, if parsimony did not save and store up, the capital would never be the greater.

Parsimony, by increasing the fund which is destined for the maintenance of productive hands, tends to increase the number of those hands whose labour adds to the value of the subject upon which it is bestowed. It tends, therefore, to increase the exchangeable value of the annual produce of the land and labour of the country. It puts into motion an additional quantity of industry, which gives an additional value to the annual produce.

What is annually saved, is as regularly consumed as what is annually spent, and nearly in the same time too: but it is consumed by a different set of people. That portion of his revenue which a rich man annually spends, is, in most cases, consumed by idle guests and menial servants, who leave nothing behind them in return for their consumption. That portion which he annually saves, as, for the sake of the profit, it is immediately employed as a capital, is consumed in the same manner, and nearly in the same time too, but by a different set of people: by labourers, manufacturers, and artificers, who reproduce, with a profit, the value of their annual consumption. His revenue, we shall suppose, is paid him in money. Had he spent the whole, the food, clothing, and lodging, which the whole could have purchased, would have been distributed among the former set of people. By saving a part of it, as that part is, for the sake of the profit, immediately employed as a capital, either by himself or by some other person, the food, clothing, and lodging, which may be purchased with it, are necessarily reserved for the latter. The consumption is the same, but the consumers are different.

By what a frugal man annually saves, he not only affords maintenance to an additional number of productive hands, for that of the ensuing year, but like the founder of a public work-house he establishes, as it were, a perpetual fund for the maintenance of an equal number in all times to come. The perpetual allotment and destination of this fund, indeed, is not always guarded by any positive law, by any trust-right or deed of mortmain. It is always guarded, however, by a very powerful principle, the plain and evident interest of every individual to whom any share of it shall ever belong. No part of it can ever afterwards be employed to maintain any but productive hands, without an evident loss to the person who thus perverts it from its proper destination.
