hate to break it to you but many blue states are net providers to the federal gov.
What it is and what its supposed to be are two different things, but if we are all supposed to be treated equal under the law, then having a tax system that favors taxpayers via deductions in one state over the taxpayers of another state is wrong. Doesnt matter about total net in or out, though i can make arguments that show blue states are actually net takers after all the federal subsidies and welfare.
