Again, you cannot logically conclude that the various measures implemented since the crisis were ineffective, since you can't argue the counterfactual.
As to the statement that 6 years after the crisis we're just as "shaky", we've had this discussion before w/Maverick, if I am not mistaken... There is just no evidence to support such a statement. Some things are undoubtedly worse (some of these things, such as the decline in employment, are a result of bigger forces that have nothing to do with policy), but there are lots and lots of things that are better. Finally, you'll have to forgive me, but I don't see a bubble, personally. Maybe, in some junky parts of the credit mkt, but not many others.
I am not arguing that the trillions of $$$ were well spent. In fact, I don't see what "spent" means in this context. My point is that Japan needs to do something about a really messy crisis that the country will undoubtedly face somewhere down the road. Abenomics is a serious attempt to do this. Of course, it's by no means certain that it will succeed. In fact, the whole situation might be so hopeless that no policy maker "appointed and paid to know better and to DO better" can save the patient. However, given the circumstances, you might as well try, since you got nothing to lose.
