Indeed, the tenor of Struve's argument is a fervent belief in the unlimited capacity for expansion of capitalist production, but the economic foundation of this optimism is rather weak. He is somewhat reticent as to what he means by the 'third persons' whom he considers the mainstay of accumulation, but his references to English occupational statistics indicate that he has in mind the various private and public servants, the liberal professions, in short the notorious _grand public_ so dear to bourgeois economists when they are completely at a loss. It is this 'great public' of which Marx said that it serves as the explanation for things which the economist cannot explain. It is obvious that, if we categorically refer to consumption by the capitalists and the workers, we do not speak of the entrepreneur as an individual, but of the capitalist class as a whole, including their hangers-on--employees, Civil Servants, liberal professions, and the like. All such 'third persons' who are certainly not lacking in any capitalist society are, as far as economics is concerned, joint consumers of the surplus value for the greater part, in so far, namely, as they are not also joint consumers of the wages of labour. These groups can only derive their purchasing power either from the wage of the proletariat or from the surplus value, if not from both; but on the whole, they are to be regarded as joint consumers of the surplus value. It follows that their consumption is already included in the consumption of the capitalist class, and if Struve tries to reintroduce them to the capitalists by sleight-of-hand as 'third persons' to save the situation and help to realise the surplus value, the shrewd profiteer will not be taken in. He will see at once that this great public is nothing but his old familiar retinue of parasites who buy his commodities with money of his own providing. No, no, indeed! Struve's 'third persons' will not do at all.
