I don't deny frauds in credit agencies. However, somebody was buying banks' CDOs? Who, ancient aliens? No, they weren't called surprime because credit agencies cheated on their rating, they were called so because they were inherently risky more than a normal mortgage ( so called ninja loans, no income, no job ). That's the people were buying this shit with the all time low rate loans. Human greed huh? That's less convenient than blaming banks for all the evil in this world
