The "fiasco" was not caused by the mortgages themselves but by the derivative trading.
depends on your definition of "fiasco".
The bubble, which was a record RE bubble BTW, WAS created by:
1) artificial rates
2) loose lending, encouraged by the Federal Gov.
this became a global nightmare due to the ridiculous risk taken on via derivatives. the underlying problem however, is the real estate bubble bursting, along with all the other bubbles at the same time, also created by loose money (equities and commodities).
derivatives trading per se, is not a bad thing. it serves a valuable purpose in decreasing risk actually, but completely unregulated can obviously be abused.
