It is perfectly true, that both the landlords and the labourers who are paid in money will finally exchange it for something else, as no one enjoys money _in kind_, except the miser; but the landlord who may spend perhaps a good deal in post-horses, dinners at inns, and menial servants, would be little likely to accept from the hop-planter the articles which he could get at the fair in exchange for his hops; and though the expenditure of the labourer is much more simple, and may be said to consist almost entirely in food and clothing, yet it is quite certain that the power of commanding a given quantity of labour can never be represented, with any approach towards correctness, by a given quantity of corn and clothing. As a matter of fact, the labourer in this country is paid in money; and while it often happens that for many years together the money-price of labour remains the same, the money-price of corn is continually altering, and the labourer may, perhaps, receive the value of twice as much corn in one year as he does in another. What an entirely false view, then, does it give of the real state of things, what a complete obscuration instead of illustration of the subject is it, to represent the demand for shoes as determined by the supply of hats, or the demand for hops by the supply of cloth, cheese, or even corn. In fact, the doctrine that one half of the commodities of a country necessarily constitute an adequate market or effectual demand for the other half, is utterly without foundation. The great producers who are the great sellers, before they can venture to think about the supplies of hats, shoes, and cloth, on which they may perhaps expend a tenth part of a tenth part of what they have brought to market, must first direct their whole attention to the replacing of their capital, and to the question whether, after replacing it, they will have realized fair profits. Whatever may be the number of intermediate acts of barter which may take place in regard to commodities—whether the producers send them to China,[20] or sell them in the place where they are produced: the question as to an adequate market for them, depends exclusively upon whether the producers can replace their capitals with ordinary profits, so as to enable them successfully to go on with their business.
