all, are all maintained by revenue; either, first, by that part of the annual produce which is originally destined for constituting a revenue to some particular persons, either as the rent of land or as the profits of stock; or, secondly, by that part which, though originally destined for replacing a capital and for maintaining productive laborers only, yet when it comes into their hands, whatever part of it is over and above their necessary subsistence, may be employed in maintaining indifferently either productive or unproductive hands. Thus, not only the great landlord or the rich merchant, but even the common workman, if his wages are considerable, may maintain a menial servant; or he may sometimes go to a play or a puppet-show, and so contribute his share toward maintaining one set of unproductive laborers; or he may pay some taxes, and thus help to maintain another set, more honorable and useful, indeed, but equally unproductive. No part of the annual produce, however, which had been originally destined to replace a capital, is ever directed toward maintaining unproductive hands, till after it has put into motion its full complement of productive labor, or all that it could put into motion in the way in which it was employed. The workman must have earned his wages by work done, before he can employ any part of them in this manner. That part too is generally but a small one. It is his spare revenue only, of which productive laborers have seldom a great deal. They generally have some, however; and in the payment of taxes the greatness of their number may compensate, in some measure, the smallness of their contribution. The rent of land and the profits of stock are everywhere, therefore, the principal sources from which unproductive hands derive their subsistence. These are the two sorts of revenue of which the
