Romney’s proposal works. Cutting tax rates by 20% costs $181 billion. Eliminating the AMT and taxes on interest, dividends and capital gains for couples with incomes below $200,000, and singles below $100,000, costs $38 billion. Filers with AGIs over $100,000 took $636 billion in itemized deductions, which taxed at 30% raises $191 billion, $28 billion less than the lost revenue. But lower rates boost tax revenues and the gap disappears!
