Adam Smith believed in individual economic decision-making because the people would be able to pursue their own interests without government input. In Adam Smith’s The Wealth Of Nations, Document C, he writes, “The [ruler] is completely discharged... no human wisdom or knowledge could ever be sufficient”. Adam Smith believed that without government interference every man can pursue his own interests in his own way. Adam Smith’s main idea was that the government should not regulate trade but rather individuals could handle their own affairs in trade and business. Adam Smith's economic theories were particularly influential in Britain, Europe and America. The Wealth of Nations had a profound effect on how the government in America was organised.
