Again, droski, how do you come to the conclusion that it was greed on the part of the consumer and stupidity on the part of the bank? Maybe the idiot that got the loan really thought he could afford it...afterall, he had a bank full of educated people telling him he could. Now he doesn't have a house and doesn't understand why.
Bottomline is the loan should have never been approved by the bank, and the hairdresser should have known they couldn't afford a $500K house. The pure greed cases are small on both sides, but it is hard for me to understand how the professionals on the banking side didn't know this wasn't right.
I'm an engineer, I don't expect you to understand what I do, but I provide a service that you can pay for. I can't come back and blame you when I screw up because you signed off on it. Sure, blame can be shared, but in the end I am the one that provided the service.
