Neither a fall in the value of money, nor a tax on raw produce, though each will raise the price, will _necessarily_ interfere with the quantity of raw produce; or with the number of people, who are both able to purchase, and willing to consume it. It is very easy to perceive why, when the capital of a country increases irregularly, wages should rise, whilst the price of corn remains stationary, or rises in a less proportion; and why, when the capital of a country diminishes, wages should fall whilst corn remains stationary, or falls in a much less proportion, and this too for a considerable time; the reason is, because labour is a commodity which cannot be increased and diminished at pleasure. If there are too few hats in the market for the demand, the price will rise, but only for a short time; for in the course of one year, by employing more capital in that trade, any reasonable addition may be made to the quantity of hats, and therefore their market price cannot long very much exceed their natural price; but it is not so with men; you cannot increase their number in one or two years when there is an increase of capital, nor can you rapidly diminish their number when capital is in a retrograde state; and therefore, the number of hands increasing or diminishing slowly, whilst the funds for the maintenance of labour increase or diminish rapidly, there must be a considerable interval before the price of labour is exactly regulated by the price of corn and necessaries; but in the case of a fall in the value of money, or of a tax on corn, there is not necessarily any excess in the supply of labour, nor any abatement of demand, and therefore there can be no reason why the labourer should sustain a real diminution of wages.
