Ok, if we go with what he says - the government needs to "inject money" into the economy to grease the wheels, prime the pump, whatever the metaphor of the month is. We've injected roughly $4 Trillion since 2009 in borrowed dollars (the stimulus has been included in the baseline since 2009, so we've spent $900B/yr in "stimulus), or put another way, we've borrowed more than the U.S. government did for the entire history of the republic in 4 years in an effort to stimulate the economy. If $4 Thousand Billion cannot stimulate demand, then government cannot stimulate demand. We've tried his approach. It didn't work. Let's move on from the failed policies of the past.
