Federal Investment Spending to Bail Out State Governments, etc., is Debt Free and Tax Free when the money spent originated not from others but from our Central Bank. Quantitative Easing (QE) adds liquidity to the economy by government spending money it never taxes back from YOU and ME.
If Krugman emphasized this point, we could sell the public on QE facilitated investment in recovery via projects for rescue of 50 state governments, energy independence, schools and hospitals, education and training, R&D, etc.
We could lower income taxes for the 99 %, we could protect savings accounts from inflation by COLA's.
These elements must be made clear by Krugman and his supporters.
