Habermas reasoned that mutual understanding produced by communicative action provides socially legitimate value-rational norms. But power structures, such as Weber's religions, bureaucracies, and markets, prescribe contaminated patterns of behavior resulting in "cultural impoverishment" similar to Weber's disenchantment. He shared Weber's fear of the domination of instrumental over value-rational action: "... instrumental rationality (as functionalist reason) has expanded from its appropriate realm of system organization into the lifeworld, and has thereby begun to erode the communicative competences of the members of that lifeworld". Instrumental motives for conformity to amoral institutional norms replace voluntarily shared norms of communicative action.
