 Whereas the doctrine of class struggle urges the lower classes to overthrow the ruling class and the existing social order for the purpose of establishing equality, the doctrine of class collaboration urges them to accept inequality as part of the natural state of things and preserve the social order.Furthermore, it holds that the state alone reconciles class antagonisms in society and that the strife which gives rise to communism can be harmonized.Some Marxists use the term class collaboration as a pejorative term describing working class organisations that do not pursue class struggle.
