It is not a fallacy to assert that economic analysis from the Hooverites is about as likely to be correct as medical advice from a hobo who lives in a culvert behind the nail parlor in the strip mall.
The hobo may be right. May be.
All of the numbers might be correct, absolutely without flaw. But they're still hobos ranting about rationally acting rational actors.
Half of the fellows at Hoover are the Very Smart People who rubber stamped the Iraq War go-ahead who are now telling us that big gubmint is the problem and the sky is about to fall.
