Gregmal while you’re right to a very great degree IMHO, it wasn’t the real estate agents who packaged these mortgages up in such a way that people confused them for AAA bonds. All along the chain of those who sold them, those who bought them, those who rated them, and those who regulated them, a ball was massively dropped because quick money could be made and damn the consequences. Those people did NOT do the work to understand the risks and did NOT take responsibility in any way that I understand the word. And by and large they didn’t pay. None of that excuses those who borrowed what they couldn’t repay, or millenials doing crap degrees, but that doesn’t make it untrue.
