Well the seeds of this disaster were sown on Greenspan’s watch, so he deserves a considerable part of the blame.
I disagree. "His watch" doesn't mean that Chairman Greenspan had any authority to control bad practices in the securities market or alter government requirements forcing lenders to make risky loans.
It wasn't Greenspan who blocked Republican attempts to tighten lending rules. It was the Democrats.
Alan Greenspan is entirely innocent in this mess, and the Dems know it. This is nothing more than their usual projection, played out in senate hearings.
It's disgusting.
