Post-materialism (20th century) politics a theory of the eclipse of material values.
In the second half of the 20th century, particularly amongst the young, the search for material utility which had underlain both capitalist and communist analyses was replaced by a priority to non-material values: quality of life, culture, the preservation of the environment. The theory has been used to explain the growth environmental or green politics. - Dictionary of Theories by Jennifer Bothamley
