depend upon two things—the amount of the fund from which saving can be made, and the strength of the dispositions which prompt to it.
(1.) The fund from which saving can be made is the surplus of the produce of labor, after supplying the necessaries of life to all concerned in the production (including those employed in replacing the materials, and keeping the fixed capital in repair). More than this surplus can not be saved under any circumstances. As much as this, though it never is saved, always might be. This surplus is the fund from which the enjoyments, as distinguished from the necessaries of the producers, are provided; it is the fund from which all are subsisted who are not themselves engaged in production, and from which all additions are made to capital. The capital of the employer forms the revenue of the laborers, and, if this exceeds the necessaries of life, it gives them a surplus which they may either expend in enjoyments or save.
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
