It has been shown in the First Book, that the price of the greater part of commodities resolves itself into three parts, of which one pays the wages of the labour, another the profits of the stock, and a third the rent of the land which had been employed in producing and bringing them to market: that there are, indeed, some commodities of which the price is made up of two of those parts only, the wages of labour, and the profits of stock; and a very few in which it consists altogether in one, the wages of labour; but that the price of every commodity necessarily resolves itself into some one or other, or all, of those three parts; every part of it which goes neither to rent nor to wages, being necessarily profit to some body. Since this is the case, it has been observed, with regard to every particular commodity, taken separately, it must be so with regard to all the commodities which compose the whole annual produce of the land and labour of every country, taken complexly. The whole price or exchangeable value of that annual produce must resolve itself into the same three parts, and be parcelled out among the different inhabitants of the country, either as the wages of their labour, the profits of their stock, or the rent of their land. But though the whole value of the annual produce of the land and labour of every country, is thus divided among, and constitutes a revenue to, its different inhabitants; yet, as in the rent of a private estate, we distinguish between the gross rent and the neat rent, so may we likewise in the revenue of all the inhabitants of a great country. The gross rent of a private estate comprehends whatever is paid by the farmer; the neat rent, what remains free to the landlord, after deducting the expense of management, of repairs, and all other necessary charges; or what, without hurting his estate, he can afford to place in his stock reserved for immediate consumption, or to spend upon his table, equipage, the ornaments of his house and furniture, his private enjoyments and amusements. His real wealth is in proportion, not to his gross, but to his neat rent. The gross revenue of all the inhabitants of a great country comprehends the whole annual produce of their land and labour; the neat revenue, what remains free to them, after deducting the expense of maintaining first, their fixed, and, secondly, their circulating capital, or what, without encroaching upon their capital, they can place in their stock reserved for immediate consumption, or spend upon their subsistence, conveniencies, and amusements. Their real wealth, too, is in proportion, not to their gross, but to their neat revenue.
