It must, however, be conceded, that the tendency of a bounty on the exportation of any commodity is to lower in a small degree the value of money. Whatever facilitates exportation, tends to accumulate money in a country; and on the contrary, whatever impedes exportation, tends to diminish it. The general effect of taxation, by raising the prices of the commodities taxed, tends to diminish exportation, and therefore to check the influx of money; and on the same principle, a bounty encourages the influx of money. This is more fully explained in the general observations on taxation. The injurious effects of the mercantile system have been fully exposed by Dr. Smith; the whole aim of that system was to raise the price of commodities, in the home market, by prohibiting foreign competition; but this system was no more injurious to the agricultural classes than to any other part of the community. By forcing capital into channels where it would not otherwise flow, it diminished the whole amount of commodities produced. The price, though permanently higher, was not sustained by scarcity, but by difficulty of production; and therefore, though the sellers of such commodities sold them for a higher price, they did not sell them, after the requisite quantity of capital was employed in producing them, at higher profits.[40] The manufacturers themselves, as consumers, had to pay an additional price for such commodities, and therefore it cannot be correctly said, that "the enhancement of price occasioned by both, (corporation laws and high duties on the importation of foreign commodities,) is every where finally paid by the landlords, farmers, and labourers of the country." It is the more necessary, to make this remark, as in the present day the authority of Adam Smith is quoted by country gentlemen for imposing similar high duties on the importation of foreign corn. Because the cost of production, and therefore the prices of various manufactured commodities, are raised to the consumer by one error in legislation, the country has been called upon, on the plea of justice, quietly to submit to fresh exactions. Because we all pay an additional price for our linen, muslin, and cottons, it is thought just that we should pay also an additional price for our corn. Because, in the general distribution of the labour of the world, we have prevented the greatest amount of productions from being obtained by that labour in manufactured commodities; we should further punish ourselves by diminishing the productive powers of the general labour in the supply of raw produce. It would be much wiser to acknowledge the errors which a mistaken policy has induced us to adopt, and immediately to commence a gradual recurrence to the sound principles of an universally free trade.
