It is not convenient to carry away all the cattle in order always to have horses, cows, and sheep whenever wanted, because they must be fed; the same holds good with corn, for it may be spoiled; the same with slaves; sometimes a man may require thousands of workmen, and sometimes none. Money demanded from those who have not got it makes it possible to get rid of all these inconveniences and to have everything that is required; and this is why the oppressor wants money. Besides which, he wants money so that his right to utilize another man's labour may not be confined to certain men but may be extended to all men who require the money. When there was no money in circulation each landlord could utilize the labour of his own serfs only; but when they agreed to demand from the peasants money which they had not, they were enabled to appropriate without distinction the labour of all men on every estate. Thus the oppressor finds it more convenient to press all his claims on labour in the shape of money, and for this sole object is it desired. To the victim from whom it is taken away money cannot be of use, either for the purpose of exchange (seeing he exchanges without money, as all nations have exchanged who had no government); nor for a measure of value, because this is fixed without him; nor for the purpose of saving, because the man whose productions are taken away cannot save; neither for payments, because an oppressed man always has more to pay than to receive; and if he does receive anything, the payment is made, not in money, but in articles of merchandise in either case; whether the workman takes his goods from his master's shop to remunerate his labour, or whether he buys the necessaries of life with his earnings in other shops, the money is required from him, and he is told by his oppressors that if he does not pay it they will refuse to give him land or bread, or will take away his cow or his horse, or condemn him to work, or put him in prison. He can only free himself from all this by selling the products of his toil, his own labour, or that of his children. He will have to sell this according to the prices established, not by a regular exchange, but by the authority which demands money of him. Under the conditions of the influence of tribute and taxes on prices,--which everywhere and always repeat themselves, as much with the land-owners in a narrow circle, as with the state on a larger scale (in which the causes of the modification of prices are as obvious to us, as the motion of the hands and feet of puppets is obvious to those who look behind the curtain and see who are the wire-pullers):--under these circumstances, to say that money is a medium of exchange and a measure of value, is at least astonishing.
