I think this has more to do with the US spending itself into debt in an unsustainable way. Up to $32T now. The interest carrying cost of that debt is soon going to surpass the entire defence budget. With no end in sight. It doesn't take an expert to see that's not fiscally responsible.
While nobody seriously thinks the US will default anytime in the near future, they're obviously going to have to keep rates low and have the Fed buy bonds with "printed" money, inflating their way out of it. There's no free lunch. Future economic prospects for the US have never been so grim in living memory, and that's not some doomsday fear-mongering, that's just basic economic theory and math. It's well known that high debt levels weigh on future economic growth. At the end of the day it has to be paid, either by raising prices of everything (inflation) or raising taxes. Both are incredibly destructive to the economy.
