Which I think is BS for numerous reasons. A few being, the income tax is not how the federal government was supposed nor should be funded. We need appropriated funds and taxes, not a slush bucket that ebbs and flows. Also, states that want to use income taxes to take care of their citizens ought to have priority and not penalize them. Encouraging subunits to be responsible for their needs is a good thing. Decentralizing services is beneficial by design, even if not as efficient. The US is huge and the needs of the states are so diverse we should leave it to the states to address their own needs.
