There is a prevailing opinion that all taxes, however levied, fall upon the land at last. Such an opinion may be useful in Britain, by checking the landed gentlemen, in whose hands our legislature is chiefly lodged, and making them preserve great regard for trade and industry; but I must confess that this principle, though first advanced by a celebrated writer, has so little appearance of reason that were it not for his authority it had never been received by anybody. Every man, to be sure, is desirous of pushing off from himself the burden of any tax which is imposed, and laying it upon others; but as every man has the same inclination, and is upon the defensive, no set of men can be supposed to prevail altogether in this contest. And why the landed gentleman should be the victim of the whole, and should not be able to defend himself as well as others are, I cannot readily imagine. All tradesmen, indeed, would willingly prey upon him and divide him among them if they could; but this inclination they always have, though no taxes were levied; and the same methods by which he guards against the imposition of tradesmen before taxes will serve him afterwards, and make them share the burden with him. No labour in any commodities that are exported can be very considerably raised in the price without losing the foreign market; and as some part of almost every manufactory is exported, this circumstance keeps the price of most species of labour nearly the same after the imposition of taxes. I may add that it has this effect upon the whole, for were any kind of labour paid beyond its proportion all hands would flock to it, and would soon sink it to a level with the rest.
