Got to love the Keynesian argument. If your stimulus efforts don’t produce the desired growth effects you can always say it would have worked if there was more stimulus. You can fail over and over increasing debt faster than GDP and claim there just needs to be more stimulus to produce growth.
I’ve yet to see one successful example of a person, corporation or country spending it’s way out of debt successfully. It always ends in a hyper inflationary money printing or a deflationary depression, but it’s different this time. Krugman’s got it all figured out.
