Naturally, it is in the interest of the trader to be on good terms with the one from whom he buys cheap as well as with the other to whom he sells dear. A nation therefore acts very imprudently if it fosters feelings of animosity in its suppliers and customers. The more friendly, the more advantageous. Such is the humanity of trade. And this hypocritical way of misusing morality for immoral purposes is the pride of the free-trade system.
