Return The Constitution To The Founders' Intent

The U.S. Constitution was intentionally designed to ensure a strong enough federal government to overcome the weaknesses of the Articles of Confederation and keep the country from dissolving into anarchy while maintaining a government limited in its authority beyond the basic necessities. Yes, we need the federal government to provide for national defense. Yes, we need the federal government to oversee interstate commerce. Yes, we need the federal government to handle treaties with other nations. I could go on, but you can read the Constitution for yourself. However, take close notice at the 10th Amendment:

The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

So, why does our federal government get involved in things that the Constiution does not delegate to it? The answer is "because it can." How is this done? Well, mostly it is done by collecting massive amounts of taxes and then redistributing that money back to the states with strings attached. For example, the Department of Education and the Congress only have authority over the education system at the state and local level because of the massive amounts of federal subsidies on education. The same is true of transportation (with the exception of interstate transportation). For decades the federal government mandated a 55 mph speed limit nationally by requiring that states pass a law to that effect in exchange for huge amounts of highway construction funds every year.
What is the solution? Well, the courts obviously haven't found a way to tell the federal government to mind its own business (they are apparently too busy making up laws about abortion rights, gay marriage rights, etc. and seem to have no interest in keeping government small and localized where it makes sense). Just as with anything, if people find loopholes to the intent of a law, the right thing to do is to close the loopholes. Therefore, I would propose a Constitional Amendment prohibiting the federal government from collecting revenues to be used for any purpose not explicitly delegated to it by the Constitution and from spending money on any such purpose. It would be the perfect companion to the 10th Amendement. It could read something like the following:

The United States shall not raise revenues nor incur debt for any purpose except as needed to exercise the powers explicitly delegated to the United States by the Constitution.

It just seems to me that it would be better for the states and local governments to raise their own revenues for their own locally-determined purposes and reduce the federal intervention in matters never intended to be nationalized. If the people of this great country then want to cede their rights in any particular area to the federal government, they can do so with the legal process for amending the Constitution. The lawmakers in Congress will still have plenty to do, but the era of pork-barrel spending and one-size-fits-all solutions would be over. Now that is music to my ears.
