Let's assume Romney releases his returns willingly and shows that he paid 0% income tax.
There are two scenarios that this happened: legally or illegally. If done illegally, then obviously his run is over, so there is no debate to be had there.
But if it was done legally, which is the point the democrats are REALLY trying to imply (or flat out accuse), is this a negative on Romney?
He followed the law and managed the laws in the most efficient and cost-effective manner. These seem like positive character traits to me. It also seems like a TERRIBLY broken system. But I wouldn't fault Romney for the system being broken.
Which leads to a second question - Wouldn't a fair tax be preferable over this so-easily broken system that we have? The rich would pay much more in taxes and you guarantee their tax rate won't be less than that of the middle-class. Even if you think they ought to pay more percentage (which is debatable) - the system becomes corrupt far too easily under the current IRS-Based structure - how is THIS better?
So the question is (not if it would hurt him politically), if Romney paid 0% in taxes, should we fault him for it? Is the 'fair tax' a better system?
