Step-by-step explanation:
The best point that highlights why the US government has limited power is that a limited government protects individual freedoms. This concept is integral to the United States' founding principles. Limited government ensures that the rights of citizens are safeguarded, and that the Constitution lists individual rights that cannot be overstepped by the government. Additionally, checks and balances and separation of powers are mechanisms set in place by the U.S. Constitution to limit government power and require the separate branches to collaborate, further protecting against the abuse of power.
