As in a civilized country there are but few commodities of which the exchangeable value arises from labour only, rent and profit contributing largely to that of the far greater part of them, so the annual produce of its labour will always be sufficient to purchase or command a much greater quantity of labour than what was employed in raising, preparing, and bringing that produce to market. If the society were annually to employ all the labour which it can annually purchase, as the quantity of labour would increase greatly every year, so the produce of every succeeding year would be of vastly greater value than that of the foregoing. But there is no country in which the whole annual produce is employed in maintaining the industrious. The idle everywhere consume a great part of it; and, according to the different proportions in which it is annually divided between these two different orders of people, its ordinary or average value must either annually increase or diminish, or continue the same from one year to another. CHAP. VII. OF THE NATURAL AND MARKET PRICE OF COMMODITIES. There is in every society or neighbourhood an ordinary or average rate, both of wages and profit, in every different employment of labour and stock. This rate is naturally regulated, as I shall show hereafter, partly by the general circumstances of the society, their riches or poverty, their advancing, stationary, or declining condition, and partly by the particular nature of each employment. There is likewise in every society or neighbourhood an ordinary or average rate of rent, which is regulated, too, as I shall shew hereafter, partly by the general circumstances of the society or neighbourhood in which the land is situated, and partly by the natural improved fertility of the land. These ordinary or average rates may be called the natural rates of wages, profit and rent, at the time and place in which they commonly prevail. When the price of any commodity is neither more nor less than what is sufficient to pay the rent of the land, the wages of the labour, and the profits of the stock employed in raising, preparing, and bringing it to market, according to their natural rates, the commodity is then sold for what may be called its natural price.
