"Our merchants frequently complain of the high wages of British labour as the cause of their manufactures being undersold in foreign markets; but they are silent about the high profits of stock. They complain of the extravagant gain of other people, but they say nothing of their own. The high profits of British stock, however, may contribute towards raising the price of British manufacture in many cases as much, and in some perhaps more, than the high wages of British labour." I allow that the monopoly of the colony trade will change, and often prejudicially, the direction of capital; but from what I have already said on the subject of profits, it will be seen that any change from one foreign trade to another, or from home to foreign trade, cannot, in my opinion, affect the rate of profits. The injury suffered will be what I have just described; there will be a worse distribution of the general capital and industry, and therefore less will be produced. The natural price of commodities will be raised, and therefore, though the consumer will be able to purchase to the same money value, he will obtain a less quantity of commodities. It will be seen too, that if it even had the effect of raising profits, it would not occasion the least alteration in prices; prices being regulated neither by wages nor profits. And does not Adam Smith agree in this opinion, when he says, that "the prices of commodities, or the value of gold and silver, as compared with commodities, depends upon the proportion between the _quantity of labour_ which is necessary, in order to bring a certain quantity of gold and silver to market, and that which is necessary to bring thither a certain quantity of any other sort of goods?" That quantity will not be affected, whether profits be high or low, or wages low or high. How then can prices be raised by high profits? CHAPTER XXIV. ON GROSS AND NET REVENUE. Adam Smith constantly magnifies the advantages which a country derives from a large gross, rather than a large net income. "In proportion as a greater share of the capital of a country is employed in agriculture," he says, "the greater will be the quantity of productive labour which it puts into motion within the country; as will likewise be the value which its employment adds to the annual produce of the land and labour of the society. After agriculture, the capital employed in manufactures puts into motion the greatest quantity of productive labour, and adds the greatest value to the annual produce. That which is employed in the trade of exportation has the least effect of any of the three."[43]
