What is the significance of American federalism?

Federalism means that two or more governments share power and exercise power over the same geographical area and population.

In fact, under the federal system implemented in the United States, the American Constitution is the authority of the national government and state governments. Conversely, the Constitution also reflects the will of the American people, whose will is the supreme power of a democratic country.

The biggest feature of federalism is decentralization, and sovereignty is shared by the Federation and the States. This not only respects the long-standing tradition of American States exercising various powers independently, but also meets the requirement of expanding central power when entering the United States.

The dual character of the American nation. Early North American immigrants abandoned everything and competed in the new world on the basis of equality by virtue of their own abilities, creating an equal and independent American nation without hierarchy.
