post-materialism

In sociology, postmaterialism is the transformation of individual values from materalist, physical, and economic to new individual values of autonomy and self-expression. The term was popularized by the political scientist Ronald Inglehart in his 1977 book The Silent Revolution, in which he discovered that the formative affluence experienced by the post-war generations was leading some of them to take their material security for granted and instead place greater importance on non-material goals such as self-expression, autonomy, freedom of speech, gender equality, and environmentalism. Inglehart argued that with increasing prosperity, such postmaterial values would gradually increase in the publics of advanced industrial societies through the process of intergenerational replacement.

The theory of intergenerational change is based on the scarcity hypothesis and the socialization hypothesis. Together, these two hypotheses carry the implication that, given long periods of material affluence, a growing part of society will embrace postmaterialist value systems, an implication that borne out internationally in the 1980s–2000s years of survey data. The postmaterial orientations acquired by each cohort during socialization have been observed to remain remarkably steady over the time-frame of multiple decades, being a more stable value-system in contrast to the more volatile political and social attitudes.
