In Adam Smith's earlier work, "The Theory of Moral Sentiments," which I think is just as important, he made the observation that the value of any government is judged in proportion to the extent that it makes its people happy.
No trabalho anterior de Adam Smith, "A Teoria dos Sentimentos Morais", que eu acho igualmente importante, ele chamou à atenção que o valor de qualquer governo é avaliado na proporção da medida em que faz  as pessoas felizes.
