In the United States’ federal system, the Constitution delineates specific authorities to the national government. Those powers not delegated to the federal government, nor prohibited to the states, are retained by the states respectively, or to the people. This principle, established by the Tenth Amendment, ensures a balance of power between the national and state levels. An example includes the power to establish and regulate education systems within a state.
This allocation of authority is crucial for maintaining a diverse and responsive government. It allows states to address unique local needs and experiment with different policies. Historically, it has fostered innovation and served as a safeguard against potential federal overreach, promoting a system where government remains closer to the populace and accountable to their specific concerns.
