Centralization

I think that Adriano is simply using the example of the United states since it is a popular and well known example of different states that may have certain different state laws, but are united under one federal government and their laws. Similarly in canada is the idea of provincial government versus federal government. Many countries have similar ideas possibly in slightly different ways, but the underlying idea is the Unity under the centralized government that creates a strong authority. For Marx, this authority is from the capitalist class and is the base of the driving ideas in that society.
