The consideration of this fact will lead to the understanding of a very important principle, which I believe has never been adverted to. It is this; that in a country where no taxation subsists, the alteration in the value of money arising from scarcity or abundance will operate in an equal proportion on the prices of all commodities; that if a commodity of 1000_l._ value rise to 1200_l._, or fall to 800_l._, a commodity of 10,000_l._ value will rise to 12,000_l._ or fall to 8000_l._; but in a country where prices are artificially raised by taxation, the abundance of money from an influx, or the exportation and consequent scarcity of it from foreign demand, will not operate in the same proportion on the prices of all commodities; some it will raise or lower 5, 6, or 12 per cent., others 3, 4, or 7 per cent. If a country were not taxed, and money should fall in value, its abundance in every market would produce similar effects in each. If meat rose 20 per cent., bread, beer, shoes, labour, and every commodity, would also rise 20 per cent.; it is necessary they should do so, to secure to each trade the same rate of profits. But this is no longer true when any of these commodities is taxed; if in that case they should all rise in proportion to the fall in the value of money, profits would be rendered unequal; in the case of the commodities taxed profits would be raised above the general level, and capital would be removed from one employment to another, till an equilibrium of profits was restored, which could only be, after the relative prices were altered. Will not this principle account for the different effects, which it was remarked were produced on the prices of commodities, from the altered value of money during the Bank-restriction? It was objected to those who contended that the currency was at that period depreciated, from the too great abundance of the paper circulation, that, if that were the fact, all commodities ought to have risen in the same proportion; but it was found that many had varied considerably more than others, and thence it was inferred that the rise of prices was owing to something affecting the value of commodities, and not to any alteration in the value of the currency. It appears however, as we have just seen, that in a country where commodities are taxed, they will not all vary in price in the same proportion, either in consequence of a rise or of a fall in the value of currency.
