“The biggest policy mistake of the last decade” is the title of an article by Ryan Cooper, and the mistake is of course austerity. (It is a very US focused piece, so Brexit is not on the map.) Cooper goes through all the academics who gave reasons why austerity was necessary and how their analysis later fell to bits. (How much they fell to bits is still a matter of dispute as far as these authors are concerned.)
Here is his concluding paragraph:
“As we have seen, the evidence for the Keynesian position is overwhelming. And that means the decade of pointless austerity has severely harmed the American economy — leaving us perhaps $3 trillion below the previous growth trend. Through a combination of bad faith, motivated reasoning, and sheer incompetence, austerians have directly created the problem their entire program was supposed to avoid. Good riddance.”
