The Free Market

Adam Smith was born into a time when nations measured wealth in gold and rulers believed prosperity came only when exports outstripped imports. He saw things differently: the wealth of a nation should be calculated by the productivity of each of its members, and the best way to maximize productivity was to allow it to function unfettered.
"[Without trade restrictions] the obvious and simple system of natural liberty establishes itself of its own accord. Every left perfectly free to pursue his own interest in his own way.... The sovereign is completely discharged from a duty [for which] no human wisdom or knowledge could ever be sufficient; the duty of superintending the industry of private people, and of directing it towards the employments most suitable to the interest of the society."
