The Federal government has expanded into areas not authorized by Article I, section 8 of the Constitution, which limits the Federal government's responsibility.
Everything else is a state or local government responsibility as outlined by the Tenth Amendment (Bill of Rights). An example of this is the Federal Department of Education. Article I does not list education as a Federal responsibility.
Liberals believe that the Federal government has unlimited power. More than the limited powers outlined in Article I. Conservatives believe that Federal power is limited to the Constitution. It is the reason we have a Constitution. So how do we have a Department of Education? No one challenged its violation of the Constitution. It has been around so long that most Americans believe it has always been a part of the Federal government. Is this what you believe?
Article I, section 8 indicates that the Congress shall have the power to lay and collect taxes, borrow money, regulate commerce, regulate bankruptcies, coin money, establish post offices and post roads, establish and regulate an army and navy, and declare war. Education of children, welfare programs, national health care or regulating energy is not listed in Article I. If the American people want the Federal government to do these things, than a Constitutional amendment is required to add these to Article I.
The parts of the Federal government that are unconstitutional consume over 50 percent of the Federal Budget or $1.8 trillion each year and are responsible for 64 percent of the $14 trillion of national debt.
Both Democrats and Republicans are responsible for this unchallenged expansion of Federal power. This is why we must cut the size of the Federal government to its Constitutional size. The only alternative is national bankruptcy.
