Adam Smith and Economic Liberalism

This is the Economika channel, and today we are talking about Adam Smith and Economic Liberalism.
The Wealth of Nations (1776) remain an indispensable book. Adam Smith, a promoter of liberalism, he says that a nation's wealth should not be measured by its gold, but by the goods and services that are available to its people. For Smith, society's progress is achieved through economic freedom. This position is contrary to mercantilism, which was the prevailing idea until then, which proposes government control over all aspects of trade and encourages the creation of artificial privileges, monopolies and barriers to trade.
Adam Smith cannot be ignored.
