As UG stated, right and left wings depend on on the situation. For example: right/left in most Western nations is different from right/left in old Communist era nations.
Right is traditionalist maintaining the historical status quo.
Left is agressive(not necessarily progressive, but at times it is)change.
In the big picture, universal view, right is not free enterprise capitalism and left is not state control socialist. In Western nations they are this way because traditionally European/North American nations were free enterprise/capitalist. Towards the end of the Soviet Union, however, the right was communist/socialist and the left was capitalist. It is all a matter of perception.
