"Every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command... But it is only for the sake of profit that any man employs a capital in the support of industry; and he will always, therefore, endeavor to employ it in the support of that industry of which the produce is likely to be of the greatest value, or to exchange for the greatest quantity either of money or of other goods... [In so doing] he generally neither intends to promote the public interest, nor knows how much he is promoting it . . . he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain. [But] he is in this, as in many other cases, led by an invisible hand to promote an end which was not part of his intention. By pursuing his own interest he frequently promotes that of the society more effectually than when he really intends to promote it.
"What is the species of domestic industry which his capital can employ, and of which the produce is likely to be of the greatest value, every individual, it is evident, can, in his local situation, judge much better than any statesman or lawgiver can do for him... To give the monopoly of the home market to the produce of domestic industry, in any particular art or manufacture, is in some measure to direct private people in what manner they ought to employ their capitals, and must, in almost all cases, be either a useless or hurtful regulation. If the produce of domestic can be brought there as cheaply as that of foreign industry, the regulation is evidently useless. If it cannot, it must generally be hurtful... If a foreign country can supply us with a commodity cheaper than we ourselves can make it, better buy it from them with some part of the produce of our own industry."
