Economists, pundits and politicians had little choice but to endorse the tax deal between President Obama and Congressional Republicans, because snapping back to pre-Bush tax rates would crush the economic recovery. But Washington exhibited not even the shadow of self-restraint and cut taxes far beyond what is needed or smart.

Newly emboldened Republicans demanded all the Bush tax cuts be extended. President Obama argued the country couldn't afford those for families in the highest tax brackets, but failed to apply such reasoning to temporary benefits bestowed on Democratic constituencies by his 2009 stimulus program.

Instead of compromising, with each side getting half of what it wanted, Washington feasted-everyone got everything they wanted and more. Business got its R&D tax credit and a temporary tax holiday on new investments. The wealthy got Bush-era tax rates and even lower rates through temporary elimination of income-triggered phase outs on deductions and personal exemptions. The poor and middle class got a temporary 33 percent cut in social security taxes.

Since Nancy Pelosi became speaker in 2007, government spending and the federal deficit have jumped from 19.6 percent of GDP and $161 billion to 25.1 percent and $1.5 trillion in 2011. Unfunded, increases in health care spending, the regulatory bureaucracy and fanciful experiments in industrial policy-windmills, electric cars and batteries, and the like-have bloated federal spending without credible plans to pay for it all.

Now Congress and the President compound those sins by both enacting additional "temporary" tax cuts that will be very difficult to ever let lapse. For example, thanks to Clinton and Bush tax cuts, the Social Security tax is the principal tax low- and middle-income workers pay-many pay zero or minimal personal income taxes.
