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

by Adam Smith

The post-office is properly a mercantile project. The government advances the expense of establishing the different offices, and of buying or hiring the necessary horses or carriages, and is repaid, with a large profit, by the duties upon what is carried. It is, perhaps, the only mercantile project which has been successfully managed by, I believe, every sort of government. The capital to be advanced is not very considerable. There is no mystery in the business. The returns are not only certain but immediate.

Princes, however, have frequently engaged in many other mercantile projects, and have been willing, like private persons, to mend their fortunes, by becoming adventurers in the common branches of trade. They have scarce ever succeeded. The profusion with which the affairs of princes are always managed, renders it almost impossible that they should. The agents of a prince regard the wealth of their master as inexhaustible; are careless at what price they buy, are careless at what price they sell, are careless at what expense they transport his goods from one place to another. Those agents frequently live with the profusion of princes; and sometimes, too, in spite of that profusion, and by a proper method of making up their accounts, acquire the fortunes of princes. It was thus, as we are told by Machiavel, that the agents of Lorenzo of Medicis, not a prince of mean abilities, carried on his trade. The republic of Florence was several times obliged to pay the debt into which their extravagance had involved him. He found it convenient, accordingly to give up the business of merchant, the business to which his family had originally owed their fortune, and, in the latter part of his life, to employ both what remained of that fortune, and the revenue of the state, of which he had the disposal, in projects and expenses more suitable to his station.

No two characters seem more inconsistent than those of trader and sovereign. If the trading spirit of the English East India company renders them very bad sovereigns, the spirit of sovereignty seems to have rendered them equally bad traders. While they were traders only, they managed their trade successfully, and were able to pay from their profits a moderate dividend to the proprietors of their stock. Since they became sovereigns, with a revenue which, it is said, was originally more than three millions sterling, they have been obliged to beg the ordinary assistance of government, in order to avoid immediate bankruptcy. In their former situation, their servants in India considered themselves as the clerks of merchants; in their present situation, those servants consider themselves as the ministers of sovereigns.

A state may sometimes derive some part of its public revenue from the interest of money, as well as from the profits of stock. If it has amassed a treasure, it may lend a part of that treasure, either to foreign states, or to its own subjects.

The canton of Berne derives a considerable revenue by lending a part of its treasure to foreign states, that is, by placing it in the public funds of the different indebted nations of Europe, chiefly in those of France and England. The security of this revenue must depend, first, upon the security of the funds in which it is placed, or upon the good faith of the government which has the management of them; and, secondly, upon the certainty or probability of the continuance of peace with the debtor nation. In the case of a war, the very first act of hostility on the part of the debtor nation might be the forfeiture of the funds of its credit. This policy of lending money to foreign states is, so far as I know peculiar to the canton of Berne.

The city of Hamburgh {See Memoire concernant les Droites et Impositions en Europe tome i p. 73.}has established a sort of public pawn-shop, which lends money to the subjects of the state, upon pledges, at six per cent. interest. This pawn-shop, or lombard, as it is called, affords a revenue, it is pretended, to the state, of a hundred and fifty thousand crowns, which, at four and sixpence the crown, amounts to £33,750 sterling.

The government of Pennsylvania, without amassing any treasure, invented a method of lending, not money, indeed, but what is equivalent to money, to its subjects. By advancing to private people, at interest, and upon land security to double the value, paper bills of credit, to be redeemed fifteen years after their date; and, in the mean time, made transferable from hand to hand, like banknotes, and declared by act of assembly to be a legal tender in all payments from one inhabitant of the province to another, it raised a moderate revenue, which went a considerable way towards defraying an annual expense of about £4,500, the whole ordinary expense of that frugal and orderly government. The success of an expedient of this kind must have depended upon three different circumstances: first, upon the demand for some other instrument of commerce, besides gold and silver money, or upon the demand for such a quantity of consumable stock as could not be had without sending abroad the greater part of their gold and silver money, in order to purchase it; secondly, upon the good credit of the government which made use of this expedient; and, thirdly, upon the moderation with which it was used, the whole value of the paper bills of credit never exceeding that of the gold and silver money which would have been necessary for carrying on their circulation, had there been no paper bills of credit. The same expedient was, upon different occasions, adopted by several other American colonies; but, from want of this moderation, it produced, in the greater part of them, much more disorder than conveniency.

The unstable and perishable nature of stock and credit, however, renders them unfit to be trusted to as the principal funds of that sure, steady, and permanent revenue, which can alone give security and dignity to government. The government of no great nation, that was advanced beyond the shepherd state, seems ever to have derived the greater part of its public revenue from such sources.

Land is a fund of more stable and permanent nature; and the rent of public lands, accordingly, has been the principal source of the public revenue of many a great nation that was much advanced beyond the shepherd state. From the produce or rent of the public lands, the ancient republics of Greece and Italy derived for a long time the greater part of that revenue which defrayed the necessary expenses of the commonwealth. The rent of the crown lands constituted for a long time the greater part of the revenue of the ancient sovereigns of Europe.

War, and the preparation for war, are the two circumstances which, in modern times, occasion the greater part of the necessary expense or all great states. But in the ancient republics of Greece and Italy, every citizen was a soldier, and both served, and prepared himself for service, at his own expense. Neither of those two circumstances, therefore, could occasion any very considerable expense to the state. The rent of a very moderate landed estate might be fully sufficient for defraying all the other necessary expenses of government.
