I agree that the US government is not blameless, but I disagree that bankers should not be blamed for their role. If a banker's value is "managing risk in lending, reducing overall risk," then the banks still failed to supply this value add.

It may also be a fair statement that the institutions did not know the value of what they were buying because of the way they were packaged. I thought that was one of the obstacles facing the bailout--how to value some/most/all of the troubled financial instruments involved. This lack of clarity seems to add to the risk.
