Finance like cooking: beware of the sauce

A good cook, when he has old meat or old fish that smell, prepares a good and strong sauce.
The meal turns out pretty good, nobody understands the basic (the expired meat or fish) and the cook is a genius.

Derivatives are created for the only purpose to cheat the customer.
He doesn't understand what he is buying, and since he doesn't understand and the reality is well disguised, the Financer is a "God".
Just like the cook, as long as you do not finish in a hospital.
