How does this strike you as an idea?
If I’m remembering correctly Article 1, section 8, has the principal duties of the federal government listed as building roads, running the Post Office, and being the central command for national defense. Then the 10th Amendment says that the states are responsible for everything else, basically. Slight oversimplification, but not far off. Where we run into trouble is that “promote the general welfare” thing at the beginning. And the socialist misinterpretation of same.
How about that’s exactly what we do? Limit DC to those three duties, and let the states take care of everything else. All that money (or at least what the states need) we send in as federal income tax, for example, goes to your state government for all the things that DC thinks is their duty but is in fact not. The states wouldn’t need nearly as much to run those programs at home, and the feds wouldn’t have all those bullshit bureaucracies that get so much money pissed away on them. Much less involved in “supporting the government”, and much more immediately reportable to the people.
Just a thought. Neuter “the king”.
