(4) A may hand over his weekly £5 to F on security. F by purchase obtains the goods which A refused to consume, and may use them (or their equivalent in other material forms) as capital for further production. If F can with this capital help to produce articles for which there is an increasing consumption, or articles which evoke and satisfy some new want, then A's action will have resulted in "saving" from the point of view of the community--_i.e._, there will be an increase of real capital; forms of capital which would otherwise have figured as over-supply have the breath of economic life put into them by an increase in general consumption. No real difficulty arises from a doubt whether the goods and services which A renounced were capable of becoming effective capital. The things he renounced were luxurious consumptive goods and services. But he could change them into effective capital in the following way:--Designing henceforth to consume only half his income, he would deliberately employ half the requisites of production which furnished his income in putting extra plant, machinery, etc., into some trade. Whether he does this himself, or incites F to do it, makes no difference; it will be done. In this way, by establishing new forms of useful capital, A can make good his saving, assuming an increase of general consumption. These are the four possible effects of A's saving from the point of view of the community-- (1) Nil. (2) Bogus or "paper" saving. (3) Over-supply of forms of capital. (4) Increase of real capital. It appears then that every act which in a modern industrial society is "saving," from the standpoint of the community, and not a mere transfer of "spending" from one person to another, consists in the production of a form of goods in its nature or position incapable of present consumption.
