I have this growing conviction that some of the people working in financial markets are something akin to black hat hackers. They continuously probe the system for bugs and weaknesses and then exploit them for profit. This "collateralization with obfuscation" exploit where it's impossible to calculate the risks of bundled investment packages should have been "patched" with legislation after the 2008 crash but wasn't. So, unsurprisingly, they go after it again.
