Smith has sometimes been characterized as someone who saw no role for government in economic life. In fact, he believed that government had an important role to play. Like most modern believers in free markets, Smith believes that the government should enforce contracts and grants patents and copyrights to encourage inventions and new ideas. He advanced the idea that a market economy would produce a satisfactory outcome for both consumers and producers. He also believed that his idea would evenly distribute society's resources.
