Why, every time Keynesian spending is tried, it fails and the excuse every time is "they need to spend more". We are in a debt crises and a spending crises, adding more is like printing more money during inflation, it makes no freaking sense. The only way the economy will get going again is cut the debt and spending, it may sting in the short run but the long term benefits will be a healthy economy not prolonged stagnation. When Volcker whipped inflation by driving interest rates to 20+% it caused short term negatives but the long term was 30 years of growth, the ONLY way to get a 30 year growth period again will be getting debt and spending under control we need the balls to do it.
There is no debt crisis in the United States. None. That's pure horseshit. If there were anything approaching a debt crisis bond rates wouldn't be at 3%.
I'm not naive enough to think we will reach agreement on all of this stuff, but let's get real about the debt crisis clap-trap.
