Fiscal austerity was the wring agenda before the crisis and it is even more wrong now
 Fiscal conservatives are opportunistically looking to  use the recession induced spike in the budget deficit to revive their  crusade for fiscalausterity. The case for fiscal austerity is based on  flawed economicanalysis and it is not supported by thoughtful budget  analysis. It was thewrong agenda before the crisis and it is even more  wrong now.Though there is understanding of the need for budget deficits  to provideshort-term Keynesian fiscal stimulus, there is little  understanding of themedium-term need for budget deficits to facilitate  the process of privatesector deleveraging and to restore growth. The U.S. economy needs a new engine of growth and  deficit-financed public investment has an important role to play.  Deficit financedinvestment can create a "virtuous" circle whereby public  investment spurs growth, in turn improving the budgetoutlook. The  fiscal austerity agenda risks creating a "vicious" circle in which  austerity slows growth, necessitatingfurther austerity.The budget  numbers show the U.S. has a health care cost problem rather than a  budget deficit problem. Fiscalausterity does not solve the health care  cost problem and it also risks undermining growth. That makes  fiscalausterity economic malpractice. Finally, the politics of fiscal austerity does a double  disservice. First, it pushes public understanding in the wrongdirection  by presenting government as the problem when the crisis has shown it is  the private sector that has failedand needs reform. Second, by  misleading the public it opens the door for all sorts of policy mischief  - most notablycutting Social Security.
