The capitalists of Department II, however, get poor reward for this Christian virtue. In spite of their abstinence, they are not only unable to expand their reproduction, but they are no longer even in the position to resume their production on its former scale. Even if the corresponding 'commodity value' is transferred from II_g_ to II_c_, it is not only the value but its actual and concrete form which matters. As the new part of the product of I now consists of money which cannot be used as a means of production, Department II, in spite of its abstinence, cannot renew its constant material capital on the old scale. As our diagram presupposes simple reproduction, its condition are thus violated in two directions: surplus value is being hoarded, and the constant capital shows a deficit. Marx's own results, then, prove that the production of gold cannot possibly find a place in either of the two departments of his diagram; the whole diagram is upset as soon as the first act of exchange between Departments I and II has been completed. As Engels remarks in his footnote, 'the analysis of the exchange of newly produced gold within the constant capital of Department I is not contained in the MS.'[94] Besides, the inconsistency would then only have been greater. The point of view we advocate is confirmed by Marx himself when he gives an exhaustive answer to the question, as striking as it is brief: 'Money in itself is not an element of actual reproduction.'[95] There is another important reason why we should put the production of money in a third and separate department of social production as a whole: Marx's diagram of simple reproduction is valid as the starting-point and foundation of the reproductive process not only for capitalism but also, _mutatis mutandis_, for every regulated and planned economic order, for instance a socialist one. However, the production of money, just like the commodity-form of the products, becomes obsolete when private ownership of the means of production is abolished. It constitutes the 'illegitimate' liabilities, the _faux frais_ of the anarchic economy under capitalism, a peculiar burden for a society based upon private enterprise, which implies the annual expenditure of a considerable amount of labour on the manufacture of products which are neither means of production nor yet consumer goods. This peculiar expenditure of labour by a society producing under capitalism will vanish in a socially planned economy. It is most adequately demonstrated by means of a separate department within the process of reproducing social capital. It is quite immaterial in this connection whether we picture a country which produces its own gold or a country which imports gold from abroad. The same expenditure of social labour which in the first case is necessary for the direct production of gold, is required in the second case to effect the exchange transactions.
