Paul Krugman's call to arms against austerity

More than four years on, austerity is being questioned as never before, not least because most countries implementing a deficit-reduction policy have failed to grow. Krugman, his blog and comments on Twitter, have become the focal point for objectors worldwide. Speaking to the Guardian to publicise the second edition of his book End This Depression Now, he argues that his battle will go on until policymakers realise that their reliance on deficit reduction is a "delusional" misreading of basic economics. But despite his persistent criticism, austerity remains the default position for most western governments.
