The Wealth of Nations_ Books 4-5 - Adam Smith [258]
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 creditor. This policy of lending money to foreign states is, so far as I know, peculiar to the canton of Berne.
The city of Hamburg has established a sort of public pawnshop, which lends money to the subjects of the state upon pledges at six per cent. interest.1 This pawnshop 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 meantime made transferable from hand to hand like bank notes, 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 £4500, 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, render 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 a 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
