So let me make the obvious point, just in case anyone missed it: the "pivot" of 2010 — when all the Very Serious People decided that the danger from debt trumped any and all concern for job creation — was an utter disaster, economic and human. It was even a disaster in fiscal terms, because a permanently depressed economy will cost far more in revenue than was saved by slashing the deficit by a few percent of GDP in the short term. Now, you might think that this post should be titled The Mistake of 2010 — but that would only be appropriate if it were truly an honest error. It wasn't. Some of the austerians were self-consciously exploiting deficit panic to promote a conservative agenda; some were slipping into deficit-scolding rather than dealing with our actual problems because it felt comfortable; some were just going along for the ride, saying what everyone else was saying. Hardly anyone in the deficit-scold camp engaged in hard thinking and careful assessment of the evidence.
There's a lot of money in being the right kind of wrong.
