The capitalist, then, may be assumed to make all the advances, and receive all the produce. His profit consists of the excess of the produce above the advances; his rate of profit is the ratio which that excess bears to the amount advanced. But what do the advances consist of?
It is, for the present, necessary to suppose, that the capitalist does not pay any rent; has not to purchase the use of any appropriated natural agent. This indeed is scarcely ever the exact truth. The agricultural capitalist, except when he is the owner of the soil he cultivates, always, or almost always, pays rent: and even in manufactures, (not to mention ground-rent,) the materials of the manufacture have generally paid rent, in some stage of their production. The nature of rent, however, we have not yet taken into consideration; and it will hereafter appear, that no practical error, on the question we are now examining, is produced by disregarding it.
If, then, leaving rent out of the question, we inquire in what it is that the advances of the capitalist, for purposes of production, consist, we shall find that they consist of wages of labour.
A large portion of the expenditure of every capitalist consists in the direct payment of wages. What does not consist of this, is composed of materials and implements, including buildings. But materials and implements are produced by labour; and as our supposed capitalist is not meant to represent a single employment, but to be a type of the productive industry of the whole country, we may suppose that he makes his own tools, and raises his own materials. He does this by means of previous advances, which, again, consist wholly of wages. If we suppose him to buy the materials and tools instead of producing them, the case is not altered: he then repays to a previous producer the wages which that previous producer has paid. It is true, he repays it to him with a profit; and if he had produced the things himself, he himself must have had that profit, on this part of his outlay, as well
