In a nutshell:
Economists like Professor Paul Krugman, who advise their peers ‘don’t touch the monetary system’ because it will hamper your career...are no better than the tobacco companies that hid their cancer studies.
If you want to understand 'money' read Professor Richard Werner. He is the only economist that I know of who is telling the truth about the scam that is the banking system.

Nothing, I repeat 'NOTHING' fundamental will be improved in the way our economy is allowed to work, until the LIE that is money and banking is exposed and reformed.
