Paul Krugman: Seriously Bad Ideas

Oxford, Britain — One thing we’ve learned in the years since the financial crisis is that seriously bad ideas — by which I mean bad ideas that appeal to the prejudices of Very Serious People — have remarkable staying power. No matter how much contrary evidence comes in, no matter how often and how badly predictions based on those ideas are proved wrong, the bad ideas just keep coming back. And they retain the power to warp policy.

What makes something qualify as a seriously bad idea? In general, to sound serious it must invoke big causes to explain big events — technical matters, like the troubles caused by sharing a currency without a common budget, don’t make the cut. It must also absolve corporate interests and the wealthy from responsibility for what went wrong, and call for hard choices and sacrifice on the part of the little people.
