THE BURNED OVER DISTRICT

Keynes has the power to be correct but sadly lacks the power to change those who prefer ideological purity to getting it right. Krugman points out this and other measures of the Austerians total failure to improve the economy by ruining it.

So the real test of Keynesian economics hasn’t come from the half-hearted efforts of the U.S. federal government to boost the economy, which were largely offset by cuts at the state and local levels. It has, instead, come from European nations like Greece and Ireland that had to impose savage fiscal austerity as a condition for receiving emergency loans — and have suffered Depression-level economic slumps, with real G.D.P. in both countries down by double digits.

This wasn’t supposed to happen, according to the ideology that dominates much of our political discourse. In March 2011, the Republican staff of Congress’s Joint Economic Committee released a report titled “Spend Less, Owe Less, Grow the Economy.” It ridiculed concerns that cutting spending in a slump would worsen that slump, arguing that spending cuts would improve consumer and business confidence, and that this might well lead to faster, not slower, growth.

They should have known better even at the time: the alleged historical examples of “expansionary austerity” they used to make their case had already been thoroughly debunked. And there was also the embarrassing fact that many on the right had prematurely declared Ireland a success story, demonstrating the virtues of spending cuts, in mid-2010, only to see the Irish slump deepen and whatever confidence investors might have felt evaporate.

Amazingly, by the way, it happened all over again this year. There were widespread proclamations that Ireland had turned the corner, proving that austerity works — and then the numbers came in, and they were as dismal as before.

No cheese up that alley but the Austerians and their Republican/Teabagger running dogs keep pushing us that way. Time to push back.
