Having endeavoured to remove one species of ill-founded jealousy, which is so prevalent among commercial nations, it may not be amiss to mention another, which seems equally groundless. Nothing is more usual, among states which have made some advances in commerce, than to look on the progress of their neighbours with a suspicious eye, to consider all trading states as their rivals, and to suppose that it is impossible for any of them to flourish, but at their expence. In opposition to this narrow and malignant opinion, I will venture to assert, that the encrease of riches and commerce in any one nation, instead of hurting, commonly promotes the riches and commerce of all its neighbours; and that a state can scarcely carry its trade and industry very far, where all the surrounding states are buried in ignorance, sloth, and barbarism.
It is obvious, that the domestic industry of a people cannot be hurt by the greatest prosperity of their neighbours; and as this branch of commerce is undoubtedly the most important in any extensive kingdom, we are so far removed from all reason of jealousy. But I go farther, and observe, that where an open communication is preserved among nations, it is impossible but the domestic industry of every one must receive an encrease from the improvements of the others. Compare the situation of GREATBRITAIN at present, with what it was two centuries ago. All the arts both of agriculture and manufactures were then extremely rude and imperfect. Every improvement, which we have since made, has arisen from our imitation of foreigners; and we ought so far to esteem it happy, that they had previously made advances in arts and ingenuity. But this intercourse is still upheld to our great advantage: Notwithstanding the advanced state of our manufactures, we daily adopt, in every art, the inventions and improvements of our neighbours. The commodity is first imported from abroad, to our great discontent, while we imagine that it drains us of our money: Afterwards, the art itself is gradually imported, to our visible advantage: Yet we continue still to repine, that our neighbours should possess any art, industry, and invention; forgetting that, had they not first instructed us, we should have been at present barbarians; and did they not still continue their instructions, the arts must fall into a state of languor, and lose that emulation and novelty, which contribute so much to their advancement.
The encrease of domestic industry lays the foundation of foreign commerce. Where a great number of commodities are raised and perfected for the home-market, there will always be found some which can be exported with advantage. But if our neighbours have no art or cultivation, they cannot take them; because they will have nothing to give in exchange. In this respect, states are in the same condition as individuals. A single man can scarcely be industrious, where all his fellow-citizens are idle.
The riches of the several members of a community contribute to encrease my riches, whatever profession I may follow. They consume the produce of my industry, and afford me the produce of theirs in return.
