A rather simplistic and myopic view. A bank's compliance is evaluated based on making whether it makes mortgages - not whether those to whom the loan is extended can pay the mortgage. The evaluation is about whether the loan is made - not whether the bank keeps it. A securitization of CRA and subprime mortgages is simply a method to pass the risk (which the bank may not have wanted to take) on to the folks (Freddie Mac, Fannie Mae, etc., aka: Federal Government) that induced them to make the questionable loans. Perhaps the banks should have kept the loans and failed themselves?
I am sorry, but you seem be unable to face the reality, or perhaps are not able to think deeper than a political talking point.
