Here's your answer, Mr Weale (see lib's post)
Ex-BIS man says QE was meant to get seized-up markets going again but that aim has morphed into inflating asset prices to get people to spend (or is it to make the rich richer?). But QE doesn't tackle the excessive debt that caused the problem in the first place. The solution to that is write-offs, restructuring, recapitalisation. But QE is la la land where nobody needs to do anything while big problems stack up unseen - mainly zombies which suck the life out of the healthy parts of the economy. And it's worse than 2007 because emerging economies have been sucked in to the world of debt/liquidity-driven bubbles. And moral hazard is now worse among bankers. He says that Japan is in a particularly bad place and that "(with QE) housing tends to be the big thing that goes wrong".
