‘By reason of the advances both in industry and science, by which man has subjugated the forces of nature, every worker can produce more, far more, in a day than he needs to consume.’[160]

Sismondi thus rightly stresses the fact that the productivity of labour is an indispensable condition for the historical foundation of exploitation. Yet he goes on to explain the actual origin of exploitation in a way typical of bourgeois economics: ‘But even though his labour produces wealth, this wealth, if he is called upon to enjoy it, will make him less and less fit for work. Besides, wealth hardly ever remains in the possession of the man who must live by the work of his hands.’[160]

Thus he makes exploitation and class antagonism the necessary spur to production, quite in accord with the followers of Ricardo and Malthus. But now he comes to the real cause of exploitation, the divorce of labour power from the means of production.

‘The worker cannot, as a rule, keep the land as his own; land, however, has a productive capacity which human labour but directs to the uses of man. The master of the land on which labour is performed, reserves a share in the fruits of labour to which his land has contributed, as his remuneration for the benefits afforded by this productive capacity.’[161]

This is called rent. And further: ‘In our state of civilisation, the worker can no longer call his own an adequate fund of objects for his consumption, enough to live while he performs the labours he has undertaken—until he has found a buyer. He no longer owns the raw materials, often coming from far away, on which he must exercise his industry. Even less does he possess that complicated and costly machinery which facilitates his work and makes it infinitely more productive. The rich man who possesses his consumption goods, his raw materials and his machines, need not work himself, for by supplying the worker with all these, he becomes in a sense the master of his work. As reward for the advantages he has put at the worker’s disposal, he takes outright the greater part of the fruits of his labour.’[162]

This is called capital profits. What remains of wealth, after the cream has been taken off twice, by landlord and capitalist, is the wage of labour, the income of the worker. And Sismondi adds: ‘He can consume it without reproduction.’[163]

Thus, Sismondi makes the fact of non-reproduction the criterion of income as distinct from capital for wages as well as for rent. In this, however, he is only right with regard to rent and the consumed part of capital profits; as for the part of the social product which is consumed in form of wages, it certainly does reproduce itself; it becomes the labour power of the wage labourer, for him a commodity by whose sale he lives, which he can bring to market again and again; for society it becomes the material form of variable capital which must reappear time and again in the aggregate reproduction of a year, if there is to be no loss.

So far so good. Hitherto we have only learned two facts: the productivity of labour permits of the exploitation of the workers by those who do not work themselves, and exploitation becomes the actual foundation of the distribution of income owing to the divorce of the worker from his means of production. But we still do not know what is capital and what income, and Sismondi proceeds to clarify this point, starting as usual with Robinson Crusoe:

‘In the eyes of the individual all wealth was nothing but a provision prepared beforehand for the time of need. Even so, he already distinguished two elements in this provision ... one part which he budgets to have at hand for immediate or almost immediate use, and the other which he will not need until it is to afford him new production. Thus one part of his corn must feed him until the next harvest, another part, reserved for sowing, is to bear fruit the following year. The formation of society and the introduction of exchange, permit to increase this seed, this fertile part of accumulated wealth, almost indefinitely, and this is what is called capital.’[164]

Balderdash would be a better name for all this. In using the analogy of seed, Sismondi here identifies means of production and capital, and this is wrong for two reasons. First, means of production are capital not intrinsically, but only under quite definite historical conditions; secondly, the concept of capital covers more than just the means of production. In capitalist society—with all the conditions Sismondi ignores—the means of production are only a part of capital, i.e. they are constant capital.
