This calls to mind an old story:
But knowing their hypocrisy, he said unto them, "Why are you putting me to the test? Bring me a dime and let me see it."
And they brought one. Then he said to them, "Whose head is this -- FDR's or Herbert Hoover's?"
They answered, "Roosevelt's."
And he said unto them, "Right. So shut up. Have you morons already forgotten the 20th Century? When the choice is between imitating what worked and what really, really didn't work, why are you pretending it's terribly complicated?"
And after that, no one dared to ask him any question.
I'm not an economist, but we've got five applicants for every single job opening. If you tell me that the best response to that situation is to lay off hundreds of thousands of teachers, I will not accept that this means that you're smarter and more expert than I am. I will instead conclude -- regardless of your prestige or position or years of study -- that you're a moral imbecile. And knowing what I know about your inability to make moral judgments I will have no reason to trust you to make complicated macroeconomic ones.
