It can never be the interest of the unproductive class to oppress the other two classes. It is the surplus produce of the land, or what remains after deducting the maintenance, first of the cultivators, and afterwards of the proprietors, that maintains and employs the unproductive class. The greater this surplus, the greater must likewise be the maintenance and employment of that class. The establishment of perfect justice, of perfect liberty, and of perfect equality, is the very simple secret which most effectually secures the highest degree of prosperity to all the three classes.
The merchants, artificers, and manufacturers of those mercantile states, which, like Holland and Hamburgh, consist chiefly of this unproductive class, are in the same manner maintained and employed altogether at the expense of the proprietors and cultivators of land. The only difference is, that those proprietors and cultivators are, the greater part of them, placed at a most inconvenient distance from the merchants, artificers, and manufacturers, whom they supply with the materials of their work and the fund of their subsistence; are the inhabitants of other countries, and the subjects of other governments.
Such mercantile states, however, are not only useful, but greatly useful, to the inhabitants of those other countries. They fill up, in some measure, a very important void; and supply the place of the merchants, artificers, and manufacturers, whom the inhabitants of those countries ought to find at home, but whom, from some defect in their policy, they do not find at home.
It can never be the interest of those landed nations, if I may call them so, to discourage or distress the industry of such mercantile states, by imposing high duties upon their trade, or upon the commodities which they furnish. Such duties, by rendering those commodities dearer, could serve only to sink the real value of the surplus produce of their own land, with which, or, what comes to the same thing, with the price of which those commodities are purchased. Such duties could only serve to
