It's not a "failed model". Japan has issues because banks committed fraud and disguised non-performing loans. There are strict rules in the US about when assets must be "marked to market". Plus the US has a growing population because we let in immigrants, which supports a growing economy. We are not close to having problems like Japan.

There are also many levers the Federal Reserve can pull to keep banks in check. As I said, they can raise and lower the reserve requirement and raise and lower the overnight lending rate. This can prevent banks from going nuts with lending, but obviously can't prevent all asset bubbles. Sometimes people are just irrational.

Frankly you seem to be using a bunch of big words and implying that they make a point. Using "ex nihilo" instead of "from nowhere" clinched it for me. Also, you spelled "keiretsu" wrong.
