The mistake central banks made in 2007-2009* was keeping monetary policy far too tight for far too long, for no real discernable reason.

Offering commentary on which particular sectors they feel are a 'bubble' is outside their purview and not particularly productive IMO, the state is not very good at picking winners.

Sorry you think the government wasn't pumping the 2006 economy enough?

2006 was too early, fair enough. But we were way too tight by late 2007 at least. We should never have let AD fall as much as it did.
