'The following solution', Bulgakov says, 'seems to us to correspond best to Marx's doctrine as a whole: The new variable capital in money-form supplied by II for both departments has its commodity equivalent in surplus value II. With reference to simple reproduction, we have already seen that the capitalists themselves must throw money into circulation to realise their surplus value, money which ultimately reverts to the pocket of the very capitalist it came from. The quantity of money required for the circulation of the surplus value is determined in accordance with the general law of commodity circulation by the value of the commodities that contained it, divided by the average amount of money turnover. This same law must apply here; the capitalists of Department II must dispose of a certain amount of money for the circulation of their surplus value, and must consequently possess certain money reserves. These reserves must be ample enough for the circulation both of that portion of the surplus value which represents the consumption fund and of that which is to be accumulated as capital.' Bulgakov further argues that it is immaterial to the question how much money is required to circulate a certain amount of commodities inside a country, whether or not some of these commodities contain any surplus value. 'In answer to the general question as to money sources inside the country, however, our solution is that the money is supplied by the producer of gold.'[304] If a country requires more money consequent upon an 'expansion of production', the production of gold will have to be increased accordingly. So here we are again: the producer of gold is again the _deus ex machina_, just as he had been for Marx. In fact, Bulgakov has sadly disappointed us in the high hopes we had of his new solution. His 'solution' of the problem does not go a step beyond Marx's own analysis. It can be reduced to three extremely simple statements as follows: (1) Question: How much money do we need for the realisation of capitalised surplus value? Answer: Just as much as is required in accordance with the general law of commodity circulation. (2) Q.: Where do the capitalists get the money for the realisation of capitalised surplus value? A.: They are supposed to have it. (3) Q.: How did the money come into the country in the first place? A.: It is provided by the producer of gold. The extreme simplicity of this method of explanation is suspicious rather than attractive. We need not trouble, however, to refute this theory which makes the gold producer the _deus ex machina_ of capitalist accumulation. Bulgakov has done it himself quite adequately. Eighty pages on, he returns to the gold producer in quite a different context, in the course of a lengthy argument against the theory of the wages fund in which he got involved for some mysterious reason. Here he suddenly displays a keen grasp of the problem:
