30%. If you reduce tax expenditures, this could bring in more revenue than currently even though the rate is lower.
That has never and will never happen. It's just an untruth at this point. A novel concept that has been proven time and again to be inaccurate.
How so? The Simpson-Bowles Commission suggested an even lower rate. There are plenty of generous deductions and credits out there that go to high income earners. There's just not the political will to reform them.
Well, obviously there are plenty of deductions that need to be gotten rid of. Romney can deduct mortgage interest, but someone making $75k can't deduct student loan interest? Ridiculous.
Anyways, obviously taxing capital gains the same as earned income would raise a ton of taxes.
