In contrast with this obvious defect, the English classical school shows a decisive advance above all in proclaiming every kind of labour as productive, thus revealing the creation of surplus value in manufacture as well as in agriculture. We say: the English classical school, because on this point Adam Smith himself occasionally relapses quietly into the Physiocrat point of view. It is only Ricardo who develops the theory of the value of labour as highly and logically as it could advance within the limits of the bourgeois approach. The consequence is that we must assume all capital investment to produce annual surplus value, in the manufacturing part of social production as a whole no less than in agriculture.[69]
On the other hand, the discovery of the productive, value-creating property of every kind of labour, alike in agriculture and in manufacture, suggested to Smith that agricultural labour, too, must produce, apart from the rent for the landowning class, a surplus for the tenant class over and above the total of their capital expenses. Thus, in addition to the replacement of capital, an annual income of the tenant class comes into being.[70]
Lastly, by a systematic elaboration of the concepts of avances primitives and avances annuelles introduced by Quesnay, which he calls fixed and circulating capital, Smith has made clear, among other things, that the manufacturing side of social production requires a fixed as well as a circulating capital. Thus he was well on the way to restoring to order the concepts of capital and revenue of society, and to describing them in precise terms. The following exposition represents the highest level of clarity which he achieved in this respect:
‘Though the whole annual produce of the land and labour of every country is, no doubt, ultimately destined for supplying the consumption of its inhabitants and for procuring a revenue to them, yet when it first comes either from the ground or from the hands of the productive labourer, it naturally divides itself into two parts. One of them, and frequently the largest, is, in the first place, destined for replacing a capital, or for renewing the provisions, materials, and finished work, which had been withdrawn from a capital; the other for constituting a revenue either to the owner of this capital, as the profit of his stock, or to some other person, as the rent of his land.’[71]
‘The gross revenue of all the inhabitants of a great country comprehends the whole annual produce of their land and labour; the neat revenue, what remains free to them after deducting the expense of maintaining, first, their fixed, and secondly, their circulating capital; or what, without encroaching upon their capital, they can place in their stock reserved for immediate consumption, or spend upon their subsistence, conveniencies, and amusements. Their real wealth too is in proportion, not to their gross, but to their neat revenue.’[72]
The concepts of total capital and income appear here in a more comprehensive and stricter form than in the Tableau Économique. The one-sided connection of social income with agriculture is severed and social income becomes a broader concept; and a broader concept of capital in its two forms, fixed and circulating capital, is made the basis of social production as a whole. Instead of the misleading differentiation of production into two departments, agriculture and industry, other categories of real importance are here brought to the fore: the distinction between capital and income and the distinction, further, between fixed and circulating capital.
Now Smith proceeds to a further analysis of the mutual relations of these categories and of how they change in the course of the social process, in production and circulation—in the reproductive process of society. He emphasises here a radical distinction between fixed and circulating capital from the point of view of the society:
‘The whole expense of maintaining the fixed capital must evidently be excluded from the neat revenue of the society. Neither the materials necessary for supporting their useful machines and instruments of trade, their profitable buildings, etc., nor the produce of the labour necessary for fashioning those materials into the proper form, can ever make any part of it. The price of that labour may indeed make a part of it; as the workmen so employed may place the whole value of their wages in their stock reserved for immediate consumption. But in other sorts of labour, both the price and the produce go to this stock, the price to that of the workmen, the produce to that of other people whose subsistence, convenience and amusements are augmented by the labour of those workmen.’[73]
Here Smith comes up against the important distinction between workers who produce means of production and those who produce consumer goods. With regard to the former he remarks that they create the value—destined to replace their wages and to serve as their income—in the form of means of production such as raw materials and instruments which in their natural form cannot be consumed. With regard to the latter category of workers, Smith observes that conversely the total product, or better that part of value contained in it which replaces the wages, the income of the workers together with its other remaining value, appears here in the form of consumer goods. (The real meaning latent in this conclusion, though Smith does not say so explicitly, is that the part of the product which represents the fixed capital employed in its production appears likewise in this form.) In the further course of our investigation we shall see how close Smith has here come to the vantage point from which Marx tackled the problem. The general conclusion, however, maintained by Smith without any further examination of the fundamental question, is that, in any case, whatever is destined for the preservation and renewal of the fixed capital of society cannot be added to society’s net income.
The position is different with regard to circulating capital. ‘But though the whole expenses of maintaining the fixed capital is thus necessarily excluded from the neat revenue of the society, it is not the same case with that of maintaining the circulating capital. Of the four parts of which this latter capital is composed, money, provisions, materials and finished work, the three last, it has already been observed, are regularly withdrawn from it and placed either in the fixed capital of the society, or in their stock reserved for immediate consumption. Whatever portion of those consumable goods is not employed in maintaining the former, goes all to the latter, and makes a part of the neat revenue of the society, besides what is necessary for maintaining the fixed capital.’[74]
