Governments as institutions gain their power, legitimate or not, from political life. They naturally inhabit the realm of polity. And the institutions of civil society derive their strength, deserved or not, from their defense and articulation of the worldviews and values of cultural life. Their natural habitat is culture. Businesses have economic power.
Governments have political power.
And civil society organizations have cultural power. None has a monopoly of power. This is the reason why we can now say that civil society, government, and business are the three key institutions of social life. Nor do the institutional powers necessarily know which social realms they inhabit and have affinity with. They may only be aware of their opposition to each other and not necessarily whether they come from the economy, polity, or culture.
