Smith on Profits and Interest
The diminution of the capital stock of the society, or of the funds destined for the maintenance of industry, however, as it lowers the
wages of labor, so it raises the profits of stock, and consequently the
interest of
money. By the
wages of labor being lowered, the owners of what stock remains in the society can bring their goods at less expense to market than before, and less stock being employed in supplying the market than before, they can sell them dearer.*70 Their goods cost them less, and they get more for them. Their profits, therefore, being augmented at both ends, can well afford a large
interest. The great fortunes so suddenly and so easily acquired in Bengal and the other British settlements in the East Indies, may satisfy us that, as the
wages of labor are very low, so the profits of stock are very high in those ruined countries. The
interest of
money is proportionally so. In Bengal,
money is frequently lent to the farmers at forty, fifty, and sixty per cent. and the succeeding crop is
mortgaged for the payment. As the profits which can afford such an
interest must eat up almost the whole rent of the landlord, so such enormous usury must in its turn eat up the greater part of those profits. Before the fall of the Roman republic, a usury of the same kind seems to have been common in the provinces, under the ruinous administration of their proconsuls. The virtuous Brutus lent
money in Cyprus at eight-and-forty*71 per cent. as we learn from the letters of Cicero.*72
