Government is the avatar of collective action. People vote for and otherwise tolerate a strong executive when they believe in "all for one and one for all". FDR was elected by a landslide on a platform of heavy government interventionism to address the Great Depression.
I think with the suburban explosion and rise of the personal automobile we’ve seen individualism trump collectivism. I don’t think we’ll ever see a new deal or social security like initiative in America until the power structures in our society are changed fundamentally.
