The terms Left and Right, at least here, are attributed to French politics leading up to the French Revolution.

 Quote:
The political terms Left and Right were coined during the French Revolution (1789–1799), referring to the seating arrangement in the French Estates General. Those who sat on the left generally opposed the monarchy and supported the revolution, including the creation of a republic and secularization,[5] while those on the right were supportive of the traditional institutions of the Old Regime. Use of the term Left became more prominent after the restoration of the French monarchy in 1815 when it was applied to the "Independents".[6] The word "wing" was appended to Left and Right in the late 19th century, usually with disparaging intent and "left-wing" was applied to those who were unorthodox in their religious or political views.

The term was later applied to a number of movements, especially republicanism during the French Revolution in the 18th century, followed by socialism,[7] including anarchism, communism and social democracy, in the 19th and 20th centuries.[8] Since then, the term left-wing has been applied to a broad range of movements[9] including civil rights movements, feminist movements, anti-war movements and environmental movements,[10][11] as well as a wide range of parties.[12][13][14] According to emeritus professor of economics, Barry Clark, "[leftists] claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated".[15]


I think maybe emeritus professor of economics Barry Clark should read Animal Farm, and enlighten himself to the results of 100 years of marxist socialism in nations like Russia, China, North Korea, Cuba, Nicaragua, Venezuela and other failed states. That have only resulted in even greater "excessive differences in status, power and wealth".

Not to mention mass graves of political dissenters.
