Gold didn't loose to fiat currency. The irresponsible policy makers and bankers issuing cheap dollar credit that did it.
The same guy that's president of the USA today is the same one who allowed 5 trillion to be printed AND put in Jerome Powell into office. It's the same guy who dismantled the SEC investigative powers, eased blatant fraud and corruption and now wants to remove Jerome Powell because the central banker is doing his job.
The dollar is tied to everything at a base input level; all resources, materials and even labour is priced in dollars.
This will change.
