Adam Smith was the founder of Laissez-Faire Capitalism, but he still believed that Capitalism must be balanced out with morality, and thus his two-part set: 1.) Wealth of Nations and 2.) the Theory of Moral Sentiments.
To put it plainly, Smith showed that capitalism is the best system (and it is), but Capitalism must be balanced out with morality.
