How to fix the world's monetary system?

The USD's design ensures bond-OWNERS receive interest in perpetuity from a class of bond-PAYERS.  While appearances are kept that bond-payers have a chance of becoming bond-owners, in reality that is nearly impossible.  That structural defect was designed and deliberate and literally trains those in the financial industry to follow the basic model of:  sell labor forward and extract a payment.  What is that?  Slavery.  This is how Wall Street makes money.

If you work in the financial industry, unless you actively do something to fix the system (as described below), you are now guilty of conspiracy to enslave the human race.  Please pass this to your boss.

Venezuela could have saved the Bolivar...

If they had recognized that the fraud was in the digital currency and not necessarily the paper currency, Venezuela could have reneged on its digital obligations, thereby increasing the value of the paper AS WELL as its future oil extractions and contracts.  The population would have retained purchasing power and strict controls over the digital would have been politically accepted with no civil unrest.

This will likely anger a very few who have "assets" denominated in digital Bolivars and paper hoarding might have become an issue (depending), however, this might be food for thought, if and when another currency undergoes attack.
