Nothing is more certain than that the spirit of a nation changes according to circumstances. While foreign trade flourishes, the minds of the monied people are turned to gain. Money, in such hands, is generally employed to procure more, not to purchase instruments of luxury; except for the consumption of those prodigal strangers who are thereby becoming daily poorer. It is this desire of becoming rich, which produces frugality. A man is always frugal while he is making a fortune; another very commonly becomes extravagant in the enjoyment of it; just so would it be with nations, were a wise statesman never to interpose. When, by the cessation of foreign trade, the mercantile part of a nation find themselves cut off from the profits they used to draw from strangers; and on the other hand, perceive the barriers of the nation gradually shutting against every article of unprofitable correspondence, they begin to withdraw their stocks from trade, and seek to place them within the country. This money is often lent to landed men, hitherto living within bounds, for two most substantial reasons. First, because there was little money to be borrowed, from the high rate of interest, owing to the great profits on foreign trade; and because the national stock was then only forming. The second, because the taste of the times was frugality. But when once the money which was formerly employed in buying up loads of work for the foreign markets, falls into the hands of landed men, they begin to acquire a taste for luxury. This taste is improved and extended by an infinity of arts, which employ the hands formerly taken up in furnishing branches of exportation. Thus by degrees we see a rich, industrious, frugal, trading nation, transformed into a rich, ingenious, luxurious, and polite nation. As the statesman formerly kept his attention fixed on the preservation of an equal balance between work and demand, and on every branch of commerce, in order to prevent the carrying off any part of the wealth already acquired; he must now direct his attention towards the effects of the domestic operations of that wealth. He was formerly interested in its accumulation; he must now guard against the consequences of this. While the bulk of a nation’s riches is in foreign trade, they do not circulate within the country; they circulate with strangers, against whom the balance is constantly found. In this case, the richest man in a state may appear among the poorest at home. In foreign countries you may hear of the wealth of a merchant, who is your next door neighbour at home, and who, from his way of living, you never knew to be worth a shilling. The circulation of money for home-consumption will then be very small; consequently, taxes must be very low; consequently, government will be poor.
