The first comprehensive analysis of the accumulation of individual capitals is given in volume i of Marx's _Capital_, section 7, chapters 22, 23. Here Marx treats of (_a_) the division of the surplus value into capital and revenue; (_b_) the circumstances which determine the accumulation of capital apart from this division, such as the degree of exploitation of labour power and labour productivity; (_c_) the growth of fixed capital relative to the circulating capital as a factor of accumulation; and (_d_) the increasing development of an industrial reserve army which is at the same time both a consequence and a prerequisite of the process of accumulation. In the course of this discussion, Marx deals with two inspired notions of bourgeois economists with regard to accumulation: the 'theory of abstinence' as held by the more vulgar economists, who proclaim that the division of surplus value into capital, and thus accumulation itself, is an ethical and heroic act of the capitalists; and the fallacy of the classical economists, their doctrine that the entire capitalised part of the surplus value is used solely for consumption by the productive workers, that is to say spent altogether on wages for the workers employed year by year. This erroneous assumption, which completely overlooks the fact that every increase of production must manifest itself not only in the increased number of employed workers but also in the increase of the material means of production (premises, tools, and, certainly, raw materials) is obviously rooted in that 'dogma' of Adam Smith which we have already discussed. Moreover, the assumption that the expenditure of a greater amount of capital on wages is sufficient to expand production, also results from the mistaken idea that the prices of all commodities are completely resolved into wages and surplus value, so that the constant capital is disregarded altogether. Strangely enough, even Ricardo who was, at any rate occasionally, aware of this element of error in Smith's doctrine, subscribes most emphatically to its ultimate inferences, mistaken though they were: 'It must be understood, that all the productions of a country are consumed; but it makes the greatest difference imaginable whether they are consumed by those who reproduce, or by those who do not reproduce another value. When we say that revenue is saved, and added to capital, what we mean is, that the portion of revenue, so said to be added to capital, is consumed by productive, instead of unproductive labourers.'[97]
