In 1894, Peter v. Struve who had already given a detailed appraisal of Nikolayon's book in an essay 'On Capitalist Development in Russia',[292] published a book in Russian,[293] criticising the theories of 'populism' from various aspects. In respect of our present problem, however, he mainly confines himself to proving, against both Vorontsov and Nikolayon, that capitalism does not cause a contraction of the home market but, on the contrary, an expansion. There can be no doubt that Nikolayon has made a blunder--the same that Sismondi had made. They each describe only a single aspect of the destructive process, performed by capitalism on the traditional forms of production by small enterprise. They saw only the resulting depression of general welfare, the impoverishment of broad strata of the population, and failed to notice that economic aspect of the process which entails the abolition of natural economy and the substitution of a commodity economy in rural districts. And this is as much as to say that, by absorbing further and further sections of formerly independent and self-sufficient producers into its own sphere, capitalism continuously transforms into commodity buyers ever new strata of people who had not before bought its commodities. In fact, the course of capitalist development is just the opposite of that pictured by the 'populists' on the model of Sismondi. Capitalism, far from ruining the home market, really sets about creating it, precisely by means of a spreading money economy. Struve in particular refutes the theory that the surplus value cannot possibly be realised on the home market. He argues as follows: The conviction that a mature capitalist society consists exclusively of entrepreneurs and workers forms the basis of Vorontsov's theory, and Nikolayon himself operates with this concept throughout. From this point of view, of course, the realisation of the capitalist aggregate product seems incomprehensible. And Vorontsov's theory is correct in so far as it states the fact that neither the capitalists' nor the workers' consumption can realise the surplus value, so that the existence of 'third persons' must be presumed.[294] But then, is it not beyond any doubt that some such 'third persons' exist in every capitalist society? The idea of Vorontsov and Nikolayon is pure fiction 'which cannot advance our understanding of any historical process whatever by a hair's breadth'.[295] There is no actual capitalist society, however highly developed, composed exclusively of capitalists and workers. 'Even in England and Wales, out of a thousand self-supporting inhabitants, 543 are engaged in industry, 172 in commerce, 140 in agriculture, 81 in casual wage labour, and 62 in the Civil Service, the liberal professions and the like.'
