The exportation of gold and silver is, in this case, not the cause, but the effect of its declension, and may even, for some little time, alleviate the misery of that declension.

The quantity of money, on the contrary, must in every country naturally increase as the value of the annual produce increases. The value of the consumable goods annually circulated within the society being greater will require a greater quantity of money to circulate them. A part of the increased produce, therefore, will naturally be employed in purchasing, wherever it is to be had, the additional quantity of gold and silver necessary for circulating the rest. The increase of those metals will in this case be the effect, not the cause, of the public prosperity. Gold and silver are purchased everywhere in the same manner. The food, clothing, and lodging, the revenue and maintenance of all those whose labour or stock is employed in bringing them from the mine to the market, is the price paid for them in Peru as well as in England. The country which has this price to pay will never be long without the quantity of those metals which it has occasion for; and no country will ever long retain a quantity which it has no occasion for.

Whatever, therefore, we may imagine the real wealth and revenue of a country to consist in, whether in the value of the annual produce of its land and labour, as plain reason seems to dictate; or in the quantity of the precious metals which circulate within it, as vulgar prejudices suppose; in either view of the matter, every prodigal appears to be a public enemy, and every frugal man a public benefactor.

The effects of misconduct are often the same as those of prodigality. Every injudicious and unsuccessful project in agriculture, mines, fisheries, trade, or manufactures, tends in the same manner to diminish the funds destined for the maintenance of productive labour. In every such project, though the capital is consumed by productive hands only, yet, as by the injudicious manner in which they are employed they do not reproduce the full value of their consumption, there must always be some diminution in what would otherwise have been the productive funds of the society.

It can seldom happen, indeed, that the circumstances of a great nation can be much affected either by the prodigality or misconduct of individuals; the profusion or imprudence of some being always more than compensated by the frugality and good conduct of others.

With regard to profusion, the principle which prompts to expense is the passion for present enjoyment; which, though sometimes violent and very difficult to be restrained, is in general only momentary and occasional. But the principle which prompts to save is the desire of bettering our condition, a desire which, though generally calm and dispassionate, comes with us from the womb, and never leaves us till we go into the grave. In the whole interval which separates those two moments, there is scarce perhaps a single instant in which any man is so perfectly and completely satisfied with his situation as to be without any wish of alteration or improvement of any kind. An augmentation of fortune is the means by which the greater part of men propose and wish to better their condition. It is the means the most vulgar and the most obvious; and the most likely way of augmenting their fortune is to save and accumulate some part of what they acquire, either regularly and annually, or upon some extraordinary occasions. Though the principle of expense, therefore, prevails in almost all men upon some occasions, and in some men upon almost all occasions, yet in the greater part of men, taking the whole course of their life at an average, the principle of frugality seems not only to predominate, but to predominate very greatly.

With regard to misconduct, the number of prudent and successful undertakings is everywhere much greater than that of injudicious and unsuccessful ones. After all our complaints of the frequency of bankruptcies, the unhappy men who fall into this misfortune make but a very small part of the whole number engaged in trade, and all other sorts of business; not much more perhaps than one in a thousand. Bankruptcy is perhaps the greatest and most humiliating calamity which can befall an innocent man. The greater part of men, therefore, are sufficiently careful to avoid it. Some, indeed, do not avoid it; as some do not avoid the gallows.
