”The Silent Revolution in Europe” was the first presentation of the intergenerational value change hypothesis. It argued that the publics of postindustrial societies are shifting from giving top priority to “Materialist” goals such as economic and physical security to placing increasingly strong emphasis on self-expression and the quality of life. Throughout history, survival has been insecure for most people, forcing them to give top priority to survival needs. But in advanced industrial societies, the economic miracles of the postwar era and the emergence of the welfare state gave rise to conditions under which much of the postwar generation grew up taking survival for granted; they give increasingly high priority to “Postmaterialist” values such as belonging, self-expression, and free choice. Because people's basic values do not change overnight, those who experienced the insecurity of World War I, the Great Depression, and World War II would continue to emphasize Materialist values, but we would expect to find an intergenerational shift toward Postmaterialist values.
