Tempest, the probably is easily understood. It's people like yourself that are living in la la land.
It's a process and over time things change. What we are in now, is a result of poor regulation. This WAS all Wall Streets fault. Even if economists in general felt the act of securitizing loans(which are assets not liabilities) was a good thing, neither they nor regulators can force the banks to do anything when it comes to their portfolio decisions unless it has to do with compliance of laws. And anyway, the act of securitizing on its own is not a bad thing, its when you couple it with fraudulent loans that makes it a bad thing. Its the bubble created by these pathetic maggots that made securitization a bad thing. You also can't blame citizens for accepting loans that were offered to them, when they themselves felt prices would keep going up. Who made the loans? Who made the CDOs? Who made credit default swaps? Who legitimized them?
lack of regulation was the problem, not the other way around
