No one is re-establishing the gold standard.
President Trump is trying to strong-arm the Fed into weakening the dollar, a move which flies in the face of using a metal-based currency.
The basic requirement for financialization and globalism is fiat currency because it allows unlimited trade deficits, unlimited capital flight, etc.
Trump wants to weaken the dollar by lowering interest rates to make imports more expensive and exports cheaper. I am merely pointing out that a gold-backed currency restricts trade deficits/surpluses and forces capital to be allocated more in its home currency base, while at the same time restricting spendthrift government policies.
As far as not going back to gold, we'll see what happens when the US (or China or the EU) bankrupts itself.
