The term classlessness has been used to describe different social phenomena.
In societies where classes have been abolished it is usually the result of a voluntary decision by the membership to form such a society, to abolish a pre-existing class structure in an existing society or to form a new one without any. This would include communes, of the modern period, such as various Utopian communities, the kibbutzim, etc. as well as revolutionary and political acts at the nation-state level such as the Paris Commune, Russian Revolution, etc. The abolition of social classes and the establishment of a classless society is the primary goal of communism, libertarian socialism and most forms of anarchism.
Classlessness also refers to the state of mind required in order to operate effectively as a social anthropologist. Anthropological training includes making assessments of and therefore becoming aware of one's own class assumptions, so that these can be set aside from conclusions reached about other societies. This may be compared to ethnocentric biases or the "neutral axiology" required by Max Weber. Otherwise conclusions reached about studied societies will likely be coloured by the anthropologist's own class values.
Classlessness can also refer to a society that has acquired pervasive and substantial social justice; where the economic upper class wields no special political power and poverty as experienced historically is virtually nonexistent. Some Scandinavian countries are held to have reached this state.
