Fareed Zakaria in Newsweek:
For the last few months, we have heard powerful, passionate arguments about the need to cut America’s massive budget deficit. Republican senators have claimed that we are in danger of permanently crippling the economy. Conservative economists and pundits warn of a Greece-like crisis, when America can borrow only at exorbitant interest rates. So when an opportunity presents itself to cut those deficits by about a third—more than $300 billion!—permanently and relatively easily, you would think that these very people would be in the lead. Far from it.
The Bush tax cuts remain the single largest cause of America’s structural deficit—that is, the deficit not caused by the collapse in tax revenues when the economy goes into recession. The Bush administration inherited budget surpluses from the Clinton administration. What turned these into deficits, even before the recession? There were three fundamental new costs—the tax cuts, the prescription-drug bill, and post-9/11 security spending (including the Iraq and Afghanistan wars). Of these the tax cuts were by far the largest, adding up to $2.3 trillion over 10 years. According to the Congressional Budget Office, nearly half the cost of all legislation enacted from 2001 to 2007 can be attributed to the tax cuts.
