Daniel Gross has a very astute observation about the re-setting of the top marginal rates under Obama's tenure:
...this return to 2001's tax rates was actually part of the Bush tax plan. The Republicans who controlled the White House and the Republicans who controlled the Congress earlier this decade decreed that all the tax cuts they passed would sunset in 2010. They put in this sunset provision to hide the long-term fiscal costs of the cuts. The Bush team and congressional supporters had seven years to manage fiscal affairs in such a way that they would be able to extend the tax cuts in 2010. But they screwed it up. Instead of controlling spending and aligning tax revenues with outlays, the Bush administration and its congressional allies ramped up spending massively—on two wars, on a prescription drug benefit for Medicare, on earmarks, etc. Oh, and along the way, they so miserably mismanaged oversight of Wall Street and the financial sector that it required the passage of a hugely expensive bailout. Even before the passage of the TARP, the prospect of extending all the Bush tax cuts was a nonstarter. Once Bush signed the $700 billion bailout measure into law, extending tax cuts was really a nonstarter. The national debt nearly doubled during the Bush years. So if you want to blame someone for raising taxes back to where they were in 2001, don't blame Obama. Blame Bush, his feckless Office of Management and Budget directors, his economic advisers, and congressional appropriators like Trent Lott and Tom DeLay.This is all too true. If the GOP hadn't dropped the ball on the economy then they might have a legitimate argument against allowing the tax rates to reset as per the original Bush plan. But they did drop the ball, and even without the necessary stimulus spending, we're currently on an unsustainable fiscal policy that must be changed. Supply side cultists cannot be allowed to argue ad nauseum that tax cuts increase long-term government revenues without showing tangible results.
