"In this case it would be very easy, there being one, and but one sure test of the advantageousness of trade in any article of commerce;--the profit that it yields. If a merchant finds it more profitable to sell his goods abroad than at home, he will send them abroad, without the help of the government. If the contrary, it is wasting just so much money to tempt him to deal abroad. If less profit is made by manufacturing silks in England than by getting them from abroad in return for cottons, whatever is spent in supporting the silk manufacture is so much pure loss." "But you do not think that this is actually the case with our English silk manufacture?" "I do not; as I prove by becoming an English silk manufacturer myself. For this very reason, I see that there is no need of the protection of government. The interference of government is either hurtful or useless. Foreign goods either are or are not cheaper than home-made goods. If they are cheaper, it is an injury to the buyer to oblige him to purchase at home. If they are not, there is no occasion to oblige him to purchase at home. He will do so by choice." "Aye; but the buyer is the last person considered in these arrangements. It is hard to discover why, if the merchant can supply more cheaply than the manufacturer, the customer should be taxed to uphold the manufacturer. I have no wish that my customers should be so taxed; for I know that instead of upholding me, they will leave me and buy elsewhere. If they and I are left free to observe the true rule of interest,--to buy in the cheapest market we can discover, and sell in the dearest, we shall find our interests agree, be fast friends, and make commerce the advantageous thing it was designed to be." "That is, an indirect source of wealth to all. How can rulers help seeing that as nothing is produced by commerce, as it is an indirect source of wealth,--a mere exchange of equivalents of a lower value which become equivalents of a higher value by the exchange,--the more direct the exchange, the more valuable it is to both parties? If a portion of the value is to be paid to a third party for deranging the terms of the bargain, the briskness of exchanges will be impaired in proportion to the diminution of their profit." "And while my customers are prevented from buying in the cheapest market, I am, by the same interference, hindered,--aye prohibited, selling in the dearest. My customers complain that my silks are higher priced than those of your country; but give me the means of a fair competition with your countrymen, and I will engage to get a higher price,--(that is, more commodities in exchange,)--in some parts of the world than any duchess in London will give me. The price would be lower to the buyer, but higher to me."
