The prodigal perverts it in this manner: By not confining his expense within his income, he encroaches upon his capital. Like him who perverts the revenues of some pious foundation to profane purposes, he pays the wages of idleness with those funds which the frugality of his forefathers had, as it were, consecrated to the maintenance of industry. By diminishing the funds destined for the employment of productive labour, he necessarily diminishes, so far as it depends upon him, the quantity of that labour which adds a value to the subject upon which it is bestowed, and, consequently, the value of the annual produce of the land and labour of the whole country, the real wealth and revenue of its inhabitants. If the prodigality of some were not compensated by the frugality of others, the conduct of every prodigal, by feeding the idle with the bread of the industrious, would tend not only to beggar himself, but to impoverish his country.
Though the expense of the prodigal should be altogether in home made, and no part of it in foreign commodities, its effect upon the productive funds of the society would still be the same. Every year there would still be a certain quantity of food and clothing, which ought to have maintained productive, employed in maintaining unproductive hands. Every year, therefore, there would still be some diminution in what would otherwise have been the value of the annual produce of the land and labour of the country.
This expense, it may be said, indeed, not being in foreign goods, and not occasioning any exportation of gold and silver, the same quantity of money would remain in the country as before. But if the quantity of food and clothing which were thus consumed by unproductive, had been distributed among productive hands, they would have reproduced, together with a profit, the full value of their consumption. The same quantity of money would, in this case, equally have remained in the country, and there would, besides, have been a reproduction of an equal value of consumable goods. There would have been two values instead of one.
