"How can the labourer be at the mercy of the upper and middle classes when these are admittedly dependent on the labourer for their very subsistence? But let us pass by this contradiction, which underlies all the teaching of Marx, and proceed to consider the consequences of accepting his theory. Let us suppose that the labourer, by working for a day, produces a table worth a pound, ten shillings of which represents the value of the wood, wear and tear of tools, rent of workshop, lighting, &c., &c., and the remaining ten shillings the wear and tear of the man, or his labour. According to Marx, the capitalist who supplies the wood, tools, workshop, &c., does so on the condition that he shall, besides being reimbursed for them by receiving ten shillings out of the price of the table, receive also, out of the other ten shillings due solely to the labourer, as large a share as he can possibly screw out of him by the threat of putting the job up to auction among his starving competitors. Let us suppose that in this way he induces the labourer to content himself with three shillings out of the ten which he has earned, and pockets seven shillings as profit. (I may observe here that Marx, with all his ingenuity, could never explain why a labourer should make a present of more than half his earnings to an employer who was absolutely dependent on him for all his wealth.) Our imaginary capitalist then, selling the table for its value - one pound, makes a profit of seven shillings. But mark what must ensue. Some rival capitalist, trading in tables on the same principle, will content himself with six shillings profit for the sake of attracting custom. He will sell the table for nineteen shillings; that is, he will allow the purchaser one shilling out of his profit as a bribe to secure his custom. The first capitalist will thus be compelled to lower his price to nineteen shillings also, and presently the competition of brisk young traders, believing in small profits and quick returns, will bring the price of tables down to thirteen and sixpence, or even lower if the reduction in price can be used as a pretext for securing another sixpence out of the labourer's three shillings. Take the price at thirteen and sixpence. if the seven shillings be indeed robbed from the labourer, then the purchaser, getting a table worth a pound for thirteen and sixpence, gets six and sixpence of the plunder, and the capitalist only sixpence; that is, the buyer is thirteen times as great a thief as the seller. But who are the buyers?"
