First, those which are accumulated and invested automatically. Very rich persons save a great deal of money that they have no desire to spend, since they have already satisfied or safeguarded all the wants of which they are conscious. Evidently this kind of saving involves no real sacrifice. To it the words of Lassalle are substantially applicable, and the claim to interest for abstinence decidedly inapplicable.
Second, savings to provide for old age and other future contingencies which are estimated as more important than any of the purposes for which the money might now be expended. Were interest abolished this kind of saving would be even greater than it is at present; for a larger total would be required to equal the fund that is now provided through the addition of interest to the principal. In a no-interest régime one thousand dollars would have to be set aside every year in order to total twenty thousand dollars in twenty years; when interest is accumulated on the savings, a smaller annual amount will suffice to produce the same fund. Inasmuch as this class of persons would save in an even greater degree without interest, it is clear that they regard the sacrifice involved as fully compensated in the resulting provision for the future. In their case sacrifice is amply rewarded by accumulation. Their claim to additional compensation in the form of interest does not seem to have any valid basis. In the words of the late Professor Devas, "there is ample reward given without any need of any interest or dividend. For the workers with heads or hands keep the property intact, ready for the owner to consume whenever convenient, when he gets infirm or sick, or when his children have grown up, and can enjoy the property with him."[141]
The third kind of saving is that which is made by persons who could spend, and have some desire to spend, more on present satisfactions, and who have already provided for all future wants in accordance with the standards of necessaries and comforts that they have adopted. Their fund for the future is already sufficient to meet all those needs which seem weightier than their present unsatisfied wants. If the surplus in question is saved it will go to supply future desires which are no more important than those for which it might be expended now. In other words, the alternatives before the prospective saver are to procure a given amount of satisfaction to-day, or to defer the same degree of satisfaction to a distant day.
In this case the inducement of interest will undoubtedly be necessary to bring about saving. As between equal amounts of satisfaction at different times, the average person will certainly prefer those of the present to those of the future. He will not decide in favour of the future unless the satisfactions then obtainable are to be greater in quantity. To this situation the rule that deferred enjoyments are worth less than present enjoyments, is strictly applicable. The increased quantity of future satisfaction which is necessary to turn the choice from the present to the future, and to determine that the surplus shall be saved rather than spent, can be provided only through interest. In this way the accumulations of interest and savings will make the future fund equivalent to a larger amount of enjoyment or utility than could be obtained if the surplus were exchanged for the goods of the present. "Interest magnifies the distant object." Whenever this magnifying power seems sufficiently great to outweigh the advantage of present over future satisfactions, the surplus will be saved instead of spent.
Among the well-to-do there is probably a considerable number of persons who take this attitude toward a considerable part of their savings. Since they would not make these savings without the inducement of interest, they regard the latter as a necessary compensation for the sacrifice of postponed enjoyment. In a general way we may say that they have a strict right to this interest on the intrinsic ground of sacrifice. Inasmuch as the community benefits by the savings, it may quite as fairly be required to pay for the antecedent sacrifices of the savers as for the inconvenience undergone by the performer of any useful labour or service.
Summing up the matter regarding the intrinsic justification of interest, we find that the titles of productivity and service do not conclusively establish the strict right of the capitalist to interest, and that the title of abstinence is morally valid for only a portion, probably a rather small portion, of the total amount of interest now received by the owners of capital. Consequently interest as a whole is not conclusively vindicated on individual grounds. If it is to be proved morally lawful its justification must be sought in extrinsic and social considerations. This inquiry will form the subject of the next chapter.
CHAPTER XIII
SOCIAL AND PRESUMPTIVE JUSTIFICATIONS OF INTEREST
As we saw in the last chapter, interest cannot be conclusively justified on the ground of either productivity or service. It is impossible to demonstrate that the capitalist has a strict right to interest because his capital produces interest, or because it renders a service to the labourer or the consumer. A part, probably a small part, of the interest now received can be fairly justified by the title of sacrifice. Some present owners of capital would not have saved had they not expected to receive interest. In their case interest may be regarded as a just compensation for the sacrifice that they underwent when they decided to save instead of consuming.
