We've known this for 30 years and you could argue it was set in motion when the 401k system and gold decoupling of the dollar happened in the 70s. The ability to print worthless dollars is too tempting.... Truthfully, the USA will never repay it's debt without a hyperinflation and reset of the money system. Most likely we are looking at the last 20 years of the petrodollar/strong dollar system no matter what way you cut it.
