capitals, the owner of one endeavouring to get possession of that employment which is occupied by another. But upon most occasions he can hope to justle that other out of this employment, by no other means but by dealing upon more reasonable terms. He must not only sell what he deals in somewhat cheaper, but in order to get it to sell, he must sometimes too buy it dearer. The demand for productive labour, by the increase of the funds which are destined for maintaining it, grows every day greater and greater. Labourers easily find employment, but the owners of capitals find it difficult to get labourers to employ. Their competition raises the wages of labour, and sinks the profits of stock. But when the profits which can be made by the use of a capital are in this manner diminished, as it were, at both ends, the price which can be paid for the use of it, that is, the rate of interest, must necessarily be diminished with them.
Mr. Locke, Mr. Law, and Mr. Montesquieu, as well as many other writers, seem to have imagined that the increase of the quantity of gold and silver, in consequence of the discovery of the Spanish West Indies, was the real cause of the lowering of the rate of interest through the greater part of Europe. Those metals, they say, having become of less value themselves, the use of any particular portion of them necessarily became of less value too, and consequently the price which could be paid for it. This notion, which at first sight seems so plausible, has been so fully exposed by Mr. Hume, that it is, perhaps, unnecessary to say anything more about it. The following very short and plain argument, however, may serve to explain more distinctly the fallacy which seems to have misled those gentlemen.
Before the discovery of the Spanish West Indies, ten percent seems to have been the common rate of interest through the greater part of Europe. It has since that time in different countries sunk to six, five, four, and three percent. Let us suppose that in every particular country the value of silver has sunk precisely in the same proportion as the rate of
