A new tax code

I have an idea to increase efficiencies for the Federal government. Instead of taxing individuals with a federal income tax, each state should be responsible for a share of the federal budget, and therefore contribute to it. In essence, the states would tax their citizens, and then pay into the Feds for their budget. The burden of each state would be determined just like the electoral college, i.e. you have more power in who becomes president, you pay more. Seems fair, doesn't it?

Having the states pay into a grander system can only lead to efficiencies. First, states are more vigilant about their budgets (except California, of course, the exception to every rule). Many have requirements to keep the budgets balanced. Having the states pressure the federal government to keep some restraint on spending would probably alleviate the drunken sailor spending. Additionally, since it's Congress -- made up of state representatives -- that passes spending measures, it will maybe be more in tune with economic realities. The state governors may also be able to knock some sense into the reps to keep spending at a minimum. Moreover, you get rid of the giant waste known as the IRS and its absurd tax code that is impossible to figure out unless you have studied it for years (i.e. you're an accountant).

Of course, the opponents of this idea will rush out saying it's unconstitutional blah blah blah. Change the Constitution in order to "create a *more* perfect Union."

Thoughts?
