Adam Smith, the father of economics, captured the essence of this wonderful human cooperation when he said, "He (the businessman) generally, indeed, 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." Adam Smith continues, "He is in this, as in many other cases, led by an invisible hand to promote an end which was no 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." And later he adds, "It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest."
