together for the greater good of society. Smith did favor some forms of government intervention, mainly to establish the ground rules for free enterprise. But it was his advocacy of laissez-faire practices that earned him favor in America, a country built on faith in the individual and distrust of authority. Laissez-faire practices have not prevented private interests from turning to the government for help on numerous occasions, however. Railroad companies accepted grants of land and public subsidies in the 19th century. Industries facing strong competition from abroad have long appealed for protections through trade policy. American agriculture, almost totally in private hands, has benefited from government assistance. Many other industries also have sought and received aid ranging from tax breaks to outright subsidies from the government. Government regulation of private industry can be divided into two categories -- economic regulation and social regulation. Economic regulation seeks, primarily, to control prices. Designed in theory to protect consumers and certain companies (usually small businesses) from more powerful companies, it often is justified on the grounds that fully competitive market conditions do not exist and therefore cannot provide such protections themselves. In many cases, however, economic regulations were developed to protect companies from what they described as destructive competition with each other.
