What is one power that belongs only to the federal government?

The power to print money is a responsibility that is exclusively assigned to the federal government. This authority is granted in the U.S. Constitution, specifically in Article I, Section 8, which outlines the powers of Congress. The federal government manages the nation's currency through the U.S. Department of the Treasury and the Federal Reserve System.

This centralized control over money printing ensures that there is a stable national currency, which is essential for trade, economic stability, and monetary policy. By contrast, issuing driver's licenses and regulating marriage are powers typically handled by state governments, while property tax collection is a local government responsibility. These distinctions underscore the realms of authority between federal and state or local jurisdictions, with printing money being a critical function of federal oversight in maintaining the country’s monetary system.
