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."1
Granting for a moment that this were true; what would be the advantage resulting to a country from the employment of a great quantity of productive labour, if, whether it employed that quantity or a smaller, its net rent and profits together would be the same. The whole produce of the land and labour of every country is divided into three portions; of these, one portion is devoted to wages, another to profits, and the other to rent. It is from the two last portions only, that any deductions can be made for taxes, or for savings; the former, if moderate, constituting always the necessary expenses of production. To an individual, with a capital of 20,000l., whose profits were 2000l. per annum, it would be a matter quite indifferent, whether his capital would employ a hundred, or a thousand men, whether the commodity produced sold for 10,000l., or for 20,000l., provided, in all cases, his profits were not diminished below 2000l. Is not the real interest of the nation similar? Provided its net real income, its rent and profits be the same, it is of no importance whether the nation consists of ten or of twelve millions of inhabitants. Its power of supporting fleets and armies, and all species
