[T]the obvious and simple system of natural liberty establishes itself of its own accord. Every man … is 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.

–Adam Smith, The Wealth of Nations, Book 4, Chapter 9
