All the effects which are produced on the profits of stock and the wages of labour, by a rise of rent and a rise of necessaries, in the natural progress of society, and increasing difficulty of production, will be produced by a rise of wages in consequence of taxation; and therefore the enjoyments of the labourer, as well as those of his employers, will be curtailed by the tax; and not by this tax particularly, but by any other which should raise an equal amount.
