Interesting idea to constrain Federal spending:
Repeal the 16th Amendment to the Constitution (ratified Feb. 3, 1913) which gives Congress the power to lay and collect taxes, and replace it with an amendment that requires each state to remit to the federal government a certain percent of its tax revenue.
Let's assume that each state would have to transfer one-third (it could be a different ratio) of its tax-and-fee revenue to the federal government. The federal government would have to constrain its spending, for it would not control its source of revenue. New programs would be severely limited because there would be no authority to finance them. This dynamic would force the creation of new programs by the states because they would still have the authority to tax. The federal government could still issue debt, but given the discipline of markets, this would be self-limiting because the government would not be able to tax in order to pay principal and interest when due. New entitlements would be limited for the same reason. Federal spending ultimately would be limited to the necessities of government. Other spending and programs would now be the states' purview.
