Unfortunately, experience suggests that once the financial press gets hold of a story, we should not expect calm and reasoned debate. "Small earthquake, nobody hurt" is not a headline that sells newspapers.

Add to the picture the typically opaque language of EITF 99-20 (a refinement to GAAP accounting for riskier ABS), and the desire for oversimplification becomes even more understandable. So now we have a motive (the greed of gullible investors), a weapon (obtuse financial engineering), and a suspect (the new favorite scapegoat the rating agencies).
