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]
If all the goods produced are thus swallowed up by human consumption, there can clearly be no room to spare in the total social product for such unconsumable means of production as tools and machinery, new materials and buildings, and consequently enlarged reproduction, too, will have to take a peculiar course. What happens—according to this odd conception—is simply that staple foodstuffs for new workers will be produced to the amount of the capitalised part of surplus value instead of the choice delicacies previously provided for the capitalist class. The classical theory of enlarged reproduction does not admit of any variations other than those connected with the production of consumer goods. After our previous observations it is not surprising that Marx could easily dispose of this elementary mistake of both Ricardo and Smith. Just as simple reproduction requires a regulated renewal of the constant capital, the material means of production, quite apart from the production of consumer goods in the necessary quantity for labourer and capitalist, equally so in the case of expanding production must part of the new additional capital be used to enlarge the constant capital, that is to add to the material means of production. Another law, Marx discovered, must also be applied here. The constant capital, continually overlooked by the classical economists, increases relative to the variable capital that is spent on wages. This is merely the capitalist expression of the general effects of increasing labour productivity. With technical progress, human labour is able to set in motion ever larger masses of means of production and to convert them into goods. In capitalist terms, this means a progressive decrease in expenses for living labour, in wages, relative to the expenses for inanimate means of production. Contrary to the assumption of Adam Smith and Ricardo, enlarged reproduction must not only start with the division of the capitalised part of the surplus value into constant and variable capital, but, as the technique of production advances, it is bound to allocate in this division ever increasing portions to the constant, and ever diminishing portions to the variable capital. This continuous qualitative change in the composition of capital is the specific manifestation of the accumulation of capital, that is to say of enlarged reproduction on the basis of capitalism.[98]
The other side of this picture of continual changes in the relation between the portions of constant and variable capital is the formation of a relative surplus population, as Marx called it, that is to say that part of the working population which exceeds the average needs of capital, and thus becomes redundant. This reserve of unemployable industrial labour (taken here in a broader sense, and including a proletariat that is dominated by merchant capital) is always present. It forms a necessary prerequisite of the sudden expansion of production in times of boom, and is another specific condition of capitalist accumulation.[99]
From the accumulation of individual capitals we can therefore deduce the following four characteristic phenomena of enlarged reproduction:
(1) The volume of enlarged reproduction is independent, within certain limits, of the growth of capital, and can transcend it. The necessary methods for achieving this are: increased exploitation of labour and natural forces, and increased labour productivity (including increased efficiency of the fixed capital).
(2) All real accumulation starts with that part of the surplus value which is intended for capitalisation being divided into constant and variable capital.
(3) Accumulation as a social process is accompanied by continuous changes in the relation between constant and variable capital, whereby that portion of capital which is invested in inanimate means of production continually increases as compared with that expended on wages.
(4) Concomitant with the accumulative process, and as a condition of the latter, there develops an industrial reserve army.
These characteristics, derived from the reproductive process as it is performed by the individual capitals, represent an enormous step forward as compared with the analyses of bourgeois economists. Now, however, our problem is to demonstrate the accumulation of the aggregate capital which originates from these movements of individual capitals, and on the basis of the diagram of simple reproduction to establish the precise relations between the aspects of value prevalent in the production of surplus value and the material considerations in the production of consumer and producer goods, with a view to accumulation.
The essential difference between enlarged reproduction and simple reproduction consists in the fact that in the latter the capitalist class and its hangers-on consume the entire surplus value, whereas in the former a part of the surplus value is set aside from the personal consumption of its owners, not for the purpose of hoarding, but in order to increase the active capital, i.e. for capitalisation. To make this possible, the new additional capital must also find the material prerequisites for its activity forthcoming. Here the concrete composition of the aggregate social product becomes important. Marx says already in volume i, when he considers the accumulation of individual capitals:
‘The annual production must in the first place furnish all those objects (use-values) from which the material components of capital, used up in the course of the year, have to be replaced. Deducting these there remains the net or surplus-product, in which the surplus-value lies. And of what does this surplus-product consist? Only of things destined to satisfy the wants and desires of the capitalist class, things which, consequently, enter into the consumption fund of the capitalists? Were that the case, the cup of surplus-value would be drained to the very dregs, and nothing but simple reproduction would ever take place.—To accumulate it is necessary to convert a portion of the surplus-product into capital. But we cannot, except by a miracle, convert into capital anything but such articles as can be employed in the labour-process (i.e. means of production), and such further articles as are suitable for the sustenance of the labourer, (i.e. means of subsistence). Consequently, a part of the annual surplus-labour must have been applied to the production of additional means of production and subsistence, over and above the quantity of these things
