Left–right political spectrum
The terms left-wing and right-wing are widely used in the United States, but as on the global level there is no firm consensus about their meaning. The only aspect that is generally agreed upon is that they are the defining opposites of the United States political spectrum. Left and right in the U.S. are generally associated with liberal and conservative respectively, although the meanings of the two sets of terms do not entirely coincide. Depending on the political affiliation of the individual using them, these terms can be spoken with varying implications. A 2005 poll of 2,209 American adults showed that "respondents generally viewed the paired concepts liberals and left-wingers and conservatives and right-wingers as possessing, respectively, generally similar political beliefs", but also showed that around ten percent fewer respondents understood the terms left and right than understood the terms liberal and conservative.
Left–right political spectrum
In the 2001 book "The Government and Politics of France", Andrew Knapp and Vincent Wright say that the main factor dividing the left and right wings in Western Europe is class. The left seeks social justice through redistributive social and economic policies, while the Right defends private property and capitalism. The nature of the conflict depends on existing social and political cleavages and on the level of economic development. Left-wing values include the belief in the power of human reason to achieve progress for the benefit of the human race, secularism, sovereignty exercised through the legislature, social justice and mistrust of strong personal political leadership. To the right, this is regularly seen as anti-clericalism, unrealistic social reform, doctrinaire socialism and class hatred. The Right are skeptical about the capacity for radical reforms to achieve human well-being while maintaining workplace competition. They believe in the established church both in itself and as an instrument of social cohesion; and believe in the need for strong political leadership to minimize social and political divisions. To the Left, this is seen as a selfish and reactionary opposition to social justice, a wish to impose doctrinaire religion on the population and a tendency to authoritarianism and repression.
