It should be noted that this failure was largely attributable to the anti-federal ideology that dominates most state governments and is willing to harm their citizens to preserve that ideology. Deep red states view any benefit of the federal government and central bank as a threat to their power. They have hitched their wagons to RayGun's false "taxpayer money" the Austrian school gold standard view of federal finance because it is easily adopted by econ illiterate voters and supports their "small gubmint" schtick.

Another co-architect of FDR's policies that lifted us out of the great depression and made it possible to be a force for good in WWII was Beardsley Ruml.
