The Wealth of Nations_ Books 4-5 - Adam Smith [323]
The public funds of the different indebted nations of Europe, particularly those of England, have by one author been represented as the accumulation of a great capital superadded to the other capital of the country, by means of which its trade is extended, its manufactures multiplied, and its lands cultivated and improved much beyond what they could have been by means of that other capital only. He does not consider that the capital which the first creditors of the public advanced to government was, from the moment in which they advanced it, a certain portion of the annual produce turned away from serving in the function of a capital to serve in that of a revenue; from maintaining productive labourers to maintain unproductive ones, and to be spent and wasted, generally in the course of the year, without even the hope of any future reproduction. In return for the capital which they advanced they obtained, indeed, an annuity in the public funds in most cases of more than equal value. This annuity, no doubt, replaced to them their capital, and enabled them to carry on their trade and business to the same or perhaps to a greater extent than before; that is, they were enabled either to borrow of other people a new capital upon the credit of this annuity, or by selling it to get from other
people a new capital of their own equal or superior to that which they had advanced to government. This new capital, however, which they in this manner either bought or borrowed of other people, must have existed in the country before, and must have been employed, as all capitals are, in maintaining productive labour. When it came into the hands of those who had advanced their money to government, though it was in some respects a new capital to them, it was not so to the country, but was only a capital withdrawn from certain employments in order to be turned towards others. Though is replaced to them what they had advanced to government, it did not replace it to the country. Had they not advanced this capital to government, there would have been in the country two capitals, two portions of the annual produce, instead of one, employed in maintaining productive labour.
When for defraying the expense of government a revenue is raised within the year from the produce of free or unmortgaged taxes, a certain portion of the revenue of private people is only turned away from maintaining one species of unproductive labour towards maintaining another. Some part of what they pay in those taxes might no doubt have been accumulated into capital, and consequently employed in maintaining productive labour; but the greater part would probably have been spent and consequently employed in maintaining unproductive labour. The public expense, however, when defrayed in this manner, no doubt hinders more or less the further accumulation of new capital; but it does not necessarily occasion the destruction of any actually existing capital.
When the public expense is defrayed by funding, it is defrayed by the annual destruction of some capital which had before existed in the country; by the perversion of some portion of the annual produce which had before been destined for the maintenance of productive labour towards that of unproductive
