all the "safeguards" the financial instruments have, didn't stopped them from crashing the economy in 2008, bitcoin is actually a response to that, I did lost my job then and had quite a hard time, now the same bankers tell me what is fraud and what is not.

In my country banks moved away from their social propose lending, and they just take high commissions for everything (eg. ATM commission for seeing how much I have in my account) and buy state bonds with deposits money, they advertise credits, but they don't actually credit businesses they credit people who don't need a credit and have enough real estate guarantees to pay the loan in full, so they won't lose interest profit.
