The question is whether Steve Keen is wrong, or wrong on the timing. A lot of the risks that he identified are still present. It's also possible that house prices will move back inline with earnings through a different mechanism, such as high inflation.
bwahahaha! did i not, not 6 months ago, that someone would say "just his timing was off and inflation would make sure he was right"....?!?!?! give it ten years and yes, he'll be right.
My personal take is that there are still a lot of risks out there (e.g. slow global recovery, double dip recession, and the GFC not actually being over), so it doesn't hurt to be cautious right now. Particularly as there don't seem to be any real bargains in general asset classes.
it doesn't hurt to be cautious full stop, bull market or not. you can still lose BIG TIME in a bull market. look at all those landbankers in Byford WA that made no money for 80% of the boom then missed thier window to sell...?
(And gold could well be in a big bubble, just to confound the Doom and Gloomers.
