The greater the produce of labor after supporting the laborers, the more there is which _can_ be saved. The same thing also partly contributes to determine how much _will_ be saved. A part of the motive to saving consists in the prospect of deriving an income from savings; in the fact that capital, employed in production, is capable of not only reproducing itself but yielding an increase. The greater the profit that can be made from capital, the stronger is the motive to its accumulation. § 2. Motive for Saving in the Surplus above Necessaries. But the disposition to save does not wholly depend on the external inducement to it; on the amount of profit to be made from savings. With the same pecuniary inducement, the inclination is very different, in different persons, and in different communities. (2.) All accumulation involves the sacrifice of a present, for the sake of a future good. This is the fundamental motive underlying the effective desire of accumulation, and is far more important than any other. It is, in short, the test of civilization. In order to induce the laboring-classes to improve their condition and save capital, it is absolutely necessary to excite in them (by education or religion) a belief in a future gain greater than the present sacrifice. It is, to be sure, the whole problem of creating character, and belongs to sociology and ethics rather than to political economy. In weighing the future against the present, the uncertainty of all things future is a leading element; and that uncertainty is of very different degrees. “All circumstances,” therefore, “increasing the probability of the provision we make for futurity being enjoyed by ourselves or others, tend” justly and reasonably “to give strength to the effective desire of accumulation. Thus a healthy climate or occupation, by increasing the probability of life, has a tendency to add to this desire. When engaged in safe occupations and living in healthy countries, men are much more apt to be frugal, than in unhealthy or hazardous occupations and in climates pernicious to human life. Sailors and soldiers are prodigals. In the West Indies, New Orleans, the East Indies, the expenditure of the inhabitants is profuse. The same people, coming to reside in the healthy parts of Europe, and not getting into the vortex of extravagant fashion, live economically. War and pestilence have always waste and luxury among the other evils that follow in their train. For similar reasons, whatever gives security to the affairs of the community is favorable to the strength of this principle. In this respect the general prevalence of law and order and the prospect of the continuance of peace and tranquillity have considerable influence.”(128)
