The Wealth of Nations

is carried on with borrowed money. The stock is at the risk of the borrower, who, as it were, insures it to the lender; and four or five per cent. may, in the greater part of trades, be both a sufficient profit upon the risk of this insurance, and a sufficient recompence for the trouble of employing the stock. But the proportion between interest and clear profit might not be the same in countries where the ordinary rate of profit was either a good deal lower, or a good deal higher. If it were a good deal lower, one half of it, perhaps, could not be afforded for interest; and more might be afforded if it were a good deal higher. In countries which are fast advancing to riches, the low rate of profit may, in the price of many commodities, compensate the high wages of labour, and enable those countries to sell as cheap as their less thriving neighbours, among whom the wages of labour may be lower. In reality, high profits tend much more to raise the price of work than high wages. If, in the linen manufacture, for example, the wages of the different working people, the flax-dressers, the spinners, the weavers, etc. should all of them be advanced twopence a-day, it would be necessary to heighten the price of a piece of linen only by a number of twopences equal to the number of people that had been employed about it, multiplied by the number of days during which they had been so employed. That part of the price of the commodity which resolved itself into the wages, would, through all the different stages of the manufacture, rise only in arithmetical proportion to this rise of wages. But if the profits of all the different employers of those working people should be raised five per cent. that part of the price of the commodity which resolved itself into profit would, through all the different stages of the manufacture, rise in geometrical proportion to this rise of profit. The employer of the flax dressers would, in selling his flax, require an additional five per cent. upon the whole value of the materials and wages which he advanced to his workmen. The employer of the spinners would require an additional five per cent. both upon the advanced price of the flax, and upon the wages of the spinners. And the employer of the weavers would require alike five per cent. both upon the advanced price of the linen-yarn, and upon the wages of the weavers. In raising the price of commodities, the rise of wages operates in the same manner as simple interest does in the accumulation of debt. The rise of profit operates like compound interest. Our merchants and master manufacturers complain much of the bad effects of high wages in raising the price, and thereby lessening the sale of their goods, both at home and abroad. They say nothing concerning the bad effects of high profits; they are silent with regard to the pernicious effects of their own gains; they complain only of those of other people.
