an extension of the concept of capital, and consequently of the problem of interest. In popular usage and in the terminology of scholars, capital was no longer “sums of money on loan” but “accumulated stocks of goods.”18
The doctrine of the unfruitfulness of money has another significance for our problem. It sheds light on the position of money within the class of things constituting private capital. Why do we include money in capital? Why is interest paid for sums of money on loan? How is it possible to use sums of money, even without lending them, so that they yield an income? There can be no doubt about the answers to these questions. Money is an acquisitive instrument only when it is exchanged for some other economic good. In this respect money may be compared with those consumption goods that form part of private capital only because they are not consumed by their owners themselves but are used for the acquisition of other goods or services by means of exchange. Money is no more acquisitive capital than these consumption goods are; the real acquisitive capital consists in the goods for which the money or the consumption goods are exchanged. Money that is lying “idle,” that is, money that is not exchanged for other goods, is not a part of capital; it produces no fruit. Money is part of the private capital of an individual only if and so far as it constitutes a means by which the individual in question can obtain other capital goods.
3 Money Not a Part of Social Capital
By social or productive capital Böhm-Bawerk means the aggregate of the products intended for employment in further production.19 If we accept the views expounded above, according to which money cannot be included among productive goods, then neither can it be included in social capital. It is true that Böhm-Bawerk includes it in social capital, as the majority of the economists that preceded him had done. This attitude follows logically from regarding money as a productive good; this is its only justification, and in endeavoring to show that money is not a productive good we have implied how baseless a justification it is.
In any case, perhaps we may suggest that those writers who include money among productive goods and consequently among capital goods are not very consistent. They usually reckon money as a part of social capital in that division of their systems where they deal with the concepts of money and capital, but certain obvious further conclusions are not drawn from this. On the contrary, where the doctrine of the nature of money as capital should logically be applied it appears to have been suddenly forgotten. In reviewing the determinants of the rate of interest, writers emphasize over and over again that it is not the greater or smaller quantity of money that is of importance, but the greater or smaller quantity of other economic goods. To reconcile this assertion, which is indubitably a correct summary of the matter, with the other assertion that money is a productive good, is simply impossible.
1 Money in the Socialist Community
It has been shown that under certain conditions, which occur the more frequently as division of labor and the differentiation of wants are extended, indirect exchange becomes inevitable; and that the evolution of indirect exchange gradually leads to the employment of a few particular commodities, or even one commodity only, as a common medium of exchange. When there is no exchange of any sort, and hence no indirect exchange, the use of media of exchange naturally remains unknown. This was the situation when the isolated household was the typical economic unit, and this, according to socialist aspirations, is what it will be again one day in that purely socialistic order where production and distribution are to be systematically regulated by a central body. This vision of the future socialistic system has not been described in detail by its prophets; and, in fact, it is not the same vision which they all see. There are some among them who allow a certain scope for exchange of economic goods and services, and so far as this is the case the continued use of money remains possible.
On the other hand, the certificates or orders that the organized society would distribute to its members cannot be regarded as money. Supposing that a receipt was given, say, to each laborer for each hour’s labor, and that the social income, so far as it was not employed for the satisfaction of collective needs or the support of those not able to work, was distributed in proportion to the number of receipts in the possession of each individual, so that each receipt represented a claim to an aliquot part of the total amount of goods to be distributed. Then the significance of any particular receipt as a means of satisfying the wants of an individual, in other words its value, would vary in proportion to the size of the total dividend. If, with the same number of hours of labor, the income of the society in a given year was only half as big as in the previous year, then the value of each receipt would likewise be halved.
The case of money is different. A decrease of fifty percent in the real social income would certainly involve a reduction in the purchasing power of money. But this reduction in the value of money need not bear any direct relation to the decrease in the size of the income. It might accidentally happen that the purchasing power of money was exactly halved also; but it need not happen so. This difference is of fundamental importance.
In fact, the exchange value of money is determined in a totally different way from that of a certificate or warrant. Titles like these are not susceptible of an independent process of valuation at all. If it is certain that a warrant or order will always be honored on demand, then its value will be equal to that of the goods to which it refers. If this certainty is not absolute, the value of the warrant will be correspondingly less.
If we suppose that a system of exchange might be developed even in a socialist society—not merely the exchange of labor certificates but, say, the exchange of consumption goods between individuals—then we may conceive of a place for the function of money even within the framework of such a society. This money would not be so frequently and variously employed as in an economic order based on private ownership of the means of production, but its use would be governed by the same fundamental principles.
These considerations dictate the attitude toward money that must be assumed by any attempt to construct an imaginary social order, if self-contradiction is to be avoided. So long as such a scheme completely excludes the free exchange of goods and services, then it follows logically that it has no need for money; but so far as any sort of exchange at all is allowed, it seems that indirect exchange achieved by means of a common medium of exchange must be permitted also.
Superficial critics of the capitalistic economic system are in the habit of directing their attacks principally against money. They are willing to permit the continuance of private ownership of the means of production and consequently, given the present stage of division of labor, of free exchange of goods also; and yet they want this exchange to be achieved without any medium, or at least without a common medium, or money. They obviously regard the use of money as harmful and hope to overcome all social evils by eliminating it. Their doctrine is derived from notions that have always been extraordinarily popular in lay circles during periods in which the use of money has been increasing.
All the processes of our economic life appear in a monetary guise; and those who do not see beneath the surface of things are only aware of monetary phenomena and remain unconscious of deeper relationships. Money is regarded as the cause of theft and murder, of deception and betrayal. Money is blamed when the prostitute sells her body and when the bribed judge perverts the law. It is money against which the moralist declaims when he wishes to oppose excessive materialism. Significantly enough avarice is called the love of money; and all evil is attributed to it.1
The confused and vague nature of such notions as these is obvious. It is not so clear whether it is thought that a return to direct exchange by itself will be able to overcome all the disadvantages of the use of money, or whether it is thought that other reforms will be necessary
