One has not fully grasped the stupidity of the the whole financial sector until one has understood derivatives. It's howling mad nonsense like derivatives that are responsible for the current worldwide economic shambles.
It's sad that 6 years after financial crisis people still blame imaginary objects for problems. The problems aren't derivatives, the problem is the government, but the main problem is YOU who believe in every shit someone tells you about. Governemt is their to create moral hazard and lure people into hell.
Derivatives are OK, they are good and needed in this world. Peoples and companies need to hedge to save their asses from unexpected things.
