Extended data:
The material foundation determines the emergence of superstructure. Conceptually and politically, the superstructure is produced to meet the needs of the economic base. Primitive clan society is based on public ownership of means of production, equal cooperation and the relationship between consumption and consumption.
Social order is adjusted by clan members according to traditional customs, so there is no special political superstructure such as armed groups and violent institutions. With the development of productivity and social division of labor, the conceptual superstructure with private concept as the core has emerged.
In order to safeguard the economic interests of the ruling class and suppress the resistance of the exploited class, a political superstructure with state power as the core and coercive means has been formed accordingly.
The superstructure of every social form is built to meet the needs of its own economic base. Once the superstructure is produced, it has relative independence, its own development law and certain historical inheritance.
On the surface, the political superstructure is an independent force that is above and divorced from society.
