Why federalism?

Buckley, Athwart History, Return to States' Rights, National Review, April 18,1956.

WFB points out that if more federal taxes are collected in state A than the federal government spends there while the reverse is true in state B, this is an intolerable affront to the principle that rich people should never have to pay a penny in taxes from which they do not personally benefit.

Oops.

I mean it is an affront to the sacred American principle of federalism.
