We may put our point in yet another way: it is clear that a quicker growth of constant as compared with variable capital, i.e. the progressive metamorphosis of the organic composition of capital, must take the material form of faster expansion of production in Department I as against production in Department II. Yet Marx’s diagram, where strict conformity of the two departments is axiomatic, precludes any such fluctuations in the rate of accumulation in either department. It is quite legitimate to suppose that under the technical conditions of progressive accumulation, society would invest ever increasing portions of the surplus value earmarked for accumulation in Department I rather than in Department II. Both departments being only branches of the same social production—supplementary enterprises, if you like, of the ‘aggregate capitalist’,—such a progressive transfer, for technical reasons, from one department to the other of a part of the accumulated surplus value would be wholly feasible, especially as it corresponds to the actual practice of capital. Yet this assumption is possible only so long as we envisage the surplus value earmarked for capitalisation purely in terms of value. The diagram, however, implies that this part of the surplus value appears in a definite material form which prescribes its capitalisation. Thus the surplus value of Department II exists as means of subsistence, and since it is as such to be only realised by Department I, this intended transfer of part of the capitalised surplus value from Department II to Department I is ruled out, first because the material form of this surplus value is obviously useless to Department I, and secondly because of the relations of exchange between the two departments which would in turn necessitate an equivalent transfer of the products of Department I into Department II. It is therefore downright impossible to achieve a faster expansion of Department I as against Department II within the limits of Marx’s diagram.
However we may regard the technological alterations of the mode of production in the course of accumulation, they cannot be accomplished without upsetting the fundamental relations of Marx’s diagram.
And further: according to Marx’s diagram, the capitalised surplus value is in each case immediately and completely absorbed by the productive process of the following period, for, apart from the portion earmarked for consumption, it has a natural form which allows of only one particular kind of employment. The diagram precludes the cashing and hoarding of surplus value in monetary form, as capital waiting to be invested. The free monetary forms of private capital, in Marx’s view, are first the money deposited gradually against the wear and tear of the fixed capital, for its eventual renewal; and secondly those amounts of money which represent realised surplus value but are still too small for investment. From the point of view of the aggregate capital, both these sources of free money capital are negligible. For if we assume that even a portion of the social surplus value is realised in monetary form for purposes of future investment, then at once the question arises: who has bought the material items of this surplus value, and who has provided the money? If the answer is: other capitalists, of course,—then, seeing that the capitalist class is represented in the diagram by the two departments, this portion of the surplus value must also be regarded as invested de facto, as employed in the productive process. And so we are back at immediate and complete investment of the surplus value.
Or does the freezing of one part of the surplus value in monetary form in the hands of certain capitalists mean that other capitalists will be left with a corresponding part of that surplus product in its material form? does the hoarding of realised surplus value by some imply that others are no longer able to realise their surplus value, since the capitalists are the only buyers of surplus value? This would mean, however, that the smooth course of reproduction and similarly of accumulation as described in the diagram would be interrupted. The result would be a crisis, due not to over-production but to a mere intention to accumulate, the kind of crisis envisaged by Sismondi.
In one passage of his Theories,[341] Marx explains in so many words that he ‘is not at all concerned in this connection with an accumulation of capital greater than can be used in the productive process and might lie idle in the banks in monetary form, with the consequence of lending abroad’. Marx refers these phenomena to the section on competition. Yet it is important to establish that his diagram veritably precludes the formation of such additional capital. Competition, however wide we may make the concept, obviously cannot create values, nor can it create capitals which are not themselves the result of the reproductive process.
The diagram thus precludes the expansion of production by leaps and bounds. It only allows of a gradual expansion which keeps strictly in step with the formation of the surplus value and is based upon the identity between realisation and capitalisation of the surplus value.
For the same reason, the diagram presumes an accumulation which affects both departments equally and therefore all branches of capitalist production. It precludes expansion of the demand by leaps and bounds just as much as it prevents a one-sided or precocious development of individual branches of capitalist production.
Thus the diagram assumes a movement of the aggregate capital which flies in the face of the actual course of capitalist development. At first sight, two facts are typical for the history of the capitalist mode of production: on the one hand the periodical expansion of the whole field of production by leaps and bounds, and on the other an extremely unequal development of the different branches of production. The history of the English cotton industry from the first quarter of the eighteenth to the seventies of the nineteenth century, the most characteristic chapter in the history of the capitalist mode of production, appears quite inexplicable from the point of view of Marx’s diagram.
Finally, the diagram contradicts the conception of the capitalist total process and its course as laid down by Marx in Capital, volume iii. This conception is based on the inherent contradiction between the unlimited expansive capacity of the productive forces and the limited expansive capacity of social consumption under conditions of capitalist distribution. Let us see how Marx describes this contradiction in detail in chapter 15 on ‘Unravelling the Internal Contradictions of the Law’ (of the declining profit rate):
‘The creation of surplus-value, assuming the necessary means of production, or sufficient accumulation of capital, to be existing, finds no other limit but the labouring population, when the rate of surplus-value, that is, the intensity of exploitation, is given; and no other limit but the intensity of exploitation, when the labouring population is given. And the capitalist process of production consists essentially of the production of surplus-value, materialised in the surplus-product, which is that aliquot portion of the produced commodities, in which unpaid labour is materialised. It must never be forgotten, that the production of this surplus-value—and the re-conversion of a portion of it into capital, or accumulation, forms an indispensable part of this production of surplus-value—is the immediate purpose and the compelling motive of capitalist production. It will not do to represent capitalist production as something which it is not, that is to say, as a production having for its immediate purpose the consumption of goods, or the production of means of enjoyment for the capitalists. (And, of course, even less for the worker. R. L.) This would be overlooking the specific character of capitalist production, which reveals itself in its innermost essence. The creation of this surplus-value is the object of the direct process of production, and this process has no other limits than those mentioned above. As soon as the available quantity of surplus-value has been materialised in commodities, surplus-value has been produced. But this production of surplus-value is but the first act of the capitalist process of production, it merely terminates the act of direct production. Capital has absorbed so much unpaid labour. With the development of the process, which expresses itself through a falling tendency of the rate of profit, the mass of surplus-value thus produced is swelled to immense dimensions. Now comes the second act of the process. The entire mass of commodities, the total product, which contains a portion which is to reproduce the constant and variable capital as well as a portion representing surplus-value, must be sold. If this is not done, or only partly accomplished, or only at prices which are below the prices of production, the labourer has been none the less exploited, but his exploitation does not realise as much for the capitalist. It may yield no surplus-value at all for him, or only realise a portion of the produced surplus-value, or it may even mean a partial or complete loss of his capital. The conditions of direct exploitation and those of the realisation of surplus-value are not identical. They are separated logically as well as by time and space. The first are only limited by the productive power of society, the last by the proportional relations of the various lines of production and by the consuming power of society. This last-named power is not determined either by the absolute productive power or by the absolute consuming power, but by the consuming power based on antagonistic conditions of distribution, which reduces the consumption of the great mass of the population to a variable minimum within more or less narrow limits. The consuming power is furthermore restricted by the tendency to accumulate, the greed for an expansion of capital and a production of surplus-value on an enlarged scale. This is a law of capitalist production imposed by incessant revolutions in the methods of production themselves, the resulting depreciation of existing capital, the general competitive struggle and the necessity of improving the product and expanding the scale of production, for the sake of self-preservation and on penalty of failure. The market must, therefore, be continually extended, so that its interrelations and the conditions regulating them assume more and more the form of a natural law independent of the producers and become ever more uncontrollable. This eternal contradiction seeks to balance itself by an expansion of the outlying fields of production. But to the extent that the productive power develops, it finds itself at variance with the narrow basis on which the conditions of consumption rest. On this self-contradictory basis it is no contradiction at all that there should be an excess of capital simultaneously with an excess of population. For while a combination of these two would indeed increase the mass of the produced surplus-value, it would at the same time intensify the contradiction between the conditions under which this surplus-value is produced and those under which it is realised.’[342]
