Oh good, bankers aren't liars, they're just massively incompetent.
Leading banks knowingly packaged good loans with terrible loans and sold them to a secondary market branded as a lump of good loans. Other banks took said lumps at face value without really understanding what was in them. They were either incompetent or uncaring as long as the money kept flowing. The entire situation still screams for a need for tighter controls and more scrutiny. I do understand how onerous that tends to be (I've worked with/at banks), but they entirely deserve it.
How does that disprove what I said? So long as the overall package fell within a certain legal model then all was good. The problem was everyone was following the same model. Think about that.
