Do you have a theory?
The Founding States feared that the federal government would become corrupt and overstep its constitutionally limited powers. And as a consequence of many generations of parents not making sure that their children are taught about the federal government’s constitutionally limited powers, this is what has happened.
For example, most of the federal spending programs established when Constitution-ignoring socialist FDR was president were wrongly established outside the framework of the Constitution, without the states amending the Constitution to grant the feds the specific powers to tax and spend for such programs.
