And the problem with "economics" is that none of the models actually reflects what happens in the real world (maybe a silhouette at best until a bubble bursts and they all stand around looking dumbfounded wondering how did that happen because that's not in their model), and that people who call themselves "economists" are complete shams too.
MOE: Uh, why don't you invite him over to dinner. Turn him from an enemy to a friend. Then when he's not expecting it... bam! The old fork in the eye.
HOMER: Do you think it might work, ~without~ the fork in the eye?
MOE: There's always a first time.
I like your post. All I would say is that who the hell cares if their models work or not? For the most part, every single model that every single economist ever made could be wrong. So what?
The issue becomes a problem when gov't uses law based on those idiotic models to force everyone to pay for nuclear weapons, "free" healthcare, wars, Social Security, et cetera. THAT is when the models are always wrong, and that is when we get skrewed.
