If you think you can squeeze more revenue out fine, but along with eliminating deductions, I would adjust the rates that most people don't pay. Two people who make $150K should pay the exact same amount. I don't care who has kids, a mortgage, is married, etc. Those are personal budgetary choices.
Also, we have to eliminate negative effective rates. If you want to say the rate is zero if you make $50K a year, fine. But tax returns should not be charity.
Now, if we really wanted to be rational. We would tie the federal budget to the previous year's revenue - 10% until the debt is payed off. Congress' job would then be to allocate the budget. I don't think this is a complicated problem to solve.
