Whatever may be the natural wealth of a people, or whatever may be the limits beyond which they cannot improve on their stock, it is probable, that no nation has ever reached those limits, or has been able to postpone its misfortunes, and the effects of misconduct, until its fund of materials, and the fertility of its soil, were exhausted, or the numbers of its people were greatly reduced. The same errors in policy, and weakness of manners, which prevent the proper use of resources, likewise check their increase, or improvement. The wealth of the state consists in the fortune of its members. The actual revenue of the state is that share of every private fortune, which the public has been accustomed to demand for national purposes. This revenue cannot be always proportioned to what may be supposed redundant in the private estate, but to what is, in some measure, thought so by the owner; and to what he may be made to spare, without intrenching on his manner of living, and without suspending his projects of expense, or of commerce. It should appear, therefore, that any immoderate increase of private expense is a prelude to national weakness: government, even while each of its subjects consumes a princely estate, may be straitened in point of revenue, and the paradox be explained by example, that the public is poor while its members are rich. We are frequently led into error by mistaking money for riches; we think that a people cannot be impoverished by a waste of money which is spent among themselves. The fact is, that men are impoverished only in two ways; either by having their gains suspended, or by having their substance consumed; and money expended at home, being circulated, and not consumed, cannot, any more than the exchange of a tally, or a counter, among a certain number of hands, tend to diminish the wealth of the company among whom it is handed about. But while money circulates at home, the necessaries of life, which are the real constituents of wealth, may be idly consumed; the industry which might be employed to increase the stock of a people, may be suspended, or turned to abuse. Great armies, maintained either at home or abroad, without any national object, are so many mouths unnecessarily opened to waste the stores of the public, and so many hands withheld from the arts by which its profits are made. Unsuccessful enterprises are so many ventures thrown away, and losses sustained, proportioned to the capital employed in the service. The Helvetii, in order to invade the Roman province of Gaul, burnt their habitations, dropt their instruments of husbandry, and consumed in one year the savings of many. The enterprise failed of success, and the nation was undone.
