Actually, Krugman believes this too.
Well, Krugman is a ******* idiot and a pariah in the community of economists.
I notice you aren't saying that I was wrong about there being massive borrowing and spending.
Wars generally include borrowing and spending. But wars do what Keynesian stimulus doesn't, they put people to work.
Instead, you are simply saying that this case doesn't count since it's war.
I'm saying a war economy doesn't fit with the Keynesian model. The idea that funds pumped into the economy with a 1 to 1 correlation to output is worthless. Eventually you run out of money to borrow - just ask the Ukraine. Such borrowing for a purpose, such as war is generally accepted by various socio-economic societies.
But that isn't what Lord Keynes sold - not at all. Keynes postulated that funds reverberate through an economy and have three and a half turns thus stimulating downstream economic activity well in excess of the principle spent and the interest compounded on the loan. Both the failures of Roosevelt and the disaster of the Nixon/Ford/Carter economy demonstrate the folly of Keynes.
World War II was simply a matter of ending unemployment and shrinking the economy. In 1943, 22% of all Americans were in the armed services, oil, gas, food, electricity, steel and many other products were allocated from the market through rationing.
Are you SERIOUSLY attempting to argue that reduction in the market along with nearly a quarter of the nation in the direct employ of the federal government is consistent with Keynesian economics?
Interesting. It makes me wonder if every example I provide you will just dismiss for whatever reasons. Out of curiosity, since we've been at war for almost a decade now, does that mean anything we've learned over these years doesn't count since it's a "war economy" ?
We in fact do not have a war economy. The issue now is that the Porkulus did NOT result in the economic activity that Keynes or the Obama administration predicted. Far from three turns, we failed to realize a single turn - we didn't break even, the incurred debt exceeds the increase in GDP.
And your idea about shipping the workforce off to war would explain a drop in unemployment, but not an increase in GDP
Building munitions increases the GNP but has zero effect on economic sustainability. Seriously, this is elementary stuff.
