necessarily dearer in consequence of such taxes; and the price of labour must always rise with the price of the labourer’s subsistence. Every commodity, therefore, which is the produce of domestic industry, though not immediately taxed itself, becomes dearer in consequence of such taxes, because the labour which produces it becomes so. Such taxes, therefore, are really equivalent, they say, to a tax upon every particular commodity produced at home. In order to put domestic upon the same footing with foreign industry, therefore, it becomes necessary, they think, to lay some duty upon every foreign commodity, equal to this enhancement of the price of the home commodities with which it can come into competition.
Whether taxes upon the necessaries of life, such as those in Great Britain upon soap, salt, leather, candles, etc. necessarily raise the price of labour, and consequently that of all other commodities, I shall consider hereafter, when I come to treat of taxes. Supposing, however, in the mean time, that they have this effect, and they have it undoubtedly, this general enhancement of the price of all commodities, in consequence of that labour, is a case which differs in the two following respects from that of a particular commodity, of which the price was enhanced by a particular tax immediately imposed upon it.
First, It might always be known with great exactness, how far the price of such a commodity could be enhanced by such a tax; but how far the general enhancement of the price of labour might affect that of every different commodity about which labour was employed, could never be known with any tolerable exactness. It would be impossible, therefore, to proportion, with any tolerable exactness, the tax of every foreign, to the enhancement of the price of every home commodity.
Secondly, Taxes upon the necessaries of life have nearly the same effect upon the circumstances of the people as a poor soil and a bad climate. Provisions are thereby rendered dearer, in the same manner as if it
