You don't have to be an orthodox Keynesian to understand that as long as the private sector is deleveraging the public sector has to borrow and spend in order to keep the economy moving forward. Spending on the original stimulus will peak soon; spending for additional unemployment insurance and the jobs bill will add about $90 billion.
You may not have to be an "orthodox Keynesian," to believe that the government can stimulate aggregate demand as a pareto-improving (or some "aggregate" utility improving) government intervention, but if you aren't an orthodox Keyesian (whatever that means), you might find yourself as a hydraulic Keynesian or neo-Keynesian. Perhaps familiarity with economics breeds an inability to understand when a non-economist such as Robert Reich makes contentious claims seem ordinary.
Corrections disputes Reich's point, and suggests that even if you don't have to be an "orthodox Keynesian," to understand government intervention is currently necessary for some reason, you have apparently heard of some secret consensus that has evaded Correction's ears.
