Analysis: It matters little is this is true, as America has not followed this model since 1980. Over the past thirty year time period government has increased it's debt to GDP ratio in a secular manner, almost as quickly as business and consumers have. Since we have not followed the "Keynesian" pattern of counter-cyclical spending and taxing, I would suggest we should have no expectation of the long-term economic stability promised to those who adhere the the "Proposed Model". Laying aside Maynard Keynes's belief that an economy could be best run without economic rents, in a state of perpetual zero interest rates, most who call themselves "Keynesian" today believe the central bank should emulate the "Proposed Model" in monetary policy as the government does with fiscal policy. Just as with fiscal policy, I point out the central bank has reduced interest rates to zero in a secular manner since 1980. The stabilizing effect of short-term microeconomic quivers in interest rates have been lost in a mistaken long-term trend which now waits to roll all avoided recessions during this period into on massive collapse in demand due to misallocated capital. I would suggest Alan Greenspan may have taken to heart far too seriously Paul Krugman's comment, “If you want a simple model for predicting the unemployment rate in the United States over the next few years, here it is: It will be what Greenspan wants it to be, plus or minus a random error reflecting the fact that he is not quite God" Alan Greenspan kept his foot on the gas pedal and we now get to see if our economy can indeed be best run without economic rents, in a state of perpetual zero interest rates - as Keynes one time suggested it might. I instead predict unpleasant results similar to the 1930s. Keynes, if anything, was pragmatic and quick to abandon any theory which was not proving immediately helpful. In fact his "General Theory" paper has an near absence of of mathematic description because Keynes believed economics was too variable to be described with formulas. I believe Keynes would have long ago abandoned Japan's twenty year repetition of alleged "Keynesian" policies which has produced little more than an economic coma and the highest government debt-to-GDP ratio among industrialized nations. As Keynes asked, "When the facts change, I change my mind – what do you do, sir?" This ability to easily discard dysfunctional and non-predictive models appears to be beyond the abilities of current doctrinaire "Keynesian" facsimiles. I see Skeeter Bug has already addressed these flaws of Keynesian implementation in a different style of presentation in the prior post. I think the fact that America has not implemented a Keynesian model since 1980 is clear to anyone. .
