A moron should not attempt to "correct" the knowledgable. Who told you the cause was "deregulation"? The REGULATORS who, of course, had no bias and were more than willing to accept blame for the problem they created, right?!?!
No such "misleading: took place (nor was it possible given Fannie and Freddie information guidelines). They knew exactly what they were getting. That the REGULATORS demanded mortgage "putbacks" as opposed to lawsuits should have been a clue.
But then had you a clue you wouldn;t be a liberal.
