I would agree with your assessment of the WEF goal. That is the push for climate change. Jamie Dimon's recent statement about the gov't taking private property to build solar and wind farms reveal what is taking place.
As for the BRICs, do not believe for a second the USD is not still there. We have over $1.5 trillion in banknotes outside the US. The govt's might turn away but the people will still use the banknotes.
Remember, the Eurodollar system has no currency in it. And we are dealing with a USD shortage.
