As I covered in this video below, the real inner core of these central bankers is called the "G30", The Group of Thirty. Though you cover the very public G20, I feel the "G30" has more sway.

They want to to start the whole thing Federal Reserve thing over again except globally and have it be based on Special Drawing Rights and precious metals. Just keep in mind the Federal Reserve system started out based on gold.
