There was a bit of deflation in 2009 or 2010, I forget, but the circumstances were entirely different, as is the total amount of money printed. There is absolutely no way on earth the US will go through widespread deflation to the point that it would cause severe economic problems, the only time the US saw a large amount of deflation after the Fed was established was the early 1930s as people cut expenditures to the bone and just saved cash rather than spending it, both corporate and citizen. The complete halting of liquidity in the economy is what caused that situation, the very basis of the US economy is far different from 90 years ago so expecting the same is foolish.
An inflationary crisis is the method the US dollar will die, pay attention to the US-Ukraine-Russia spat right now, Biden keeps bragging about how sanctions will crush Russia but it completely misses the point that Russia is largely disconnected from the global economy the US dominates, has very low debt-to-gdp and I believe has a very large gold reserve explicitly for this purpose, something near 600b in gold reserves, far larger than the US Dollar reserves. Sanctioning Russia screws over the EU, not Russia, furthermore China will accept gold to ensure its belt-and-road project's success, if anything gold is a better option for China to accept than taking on more US Dollars, Biden is actively going to destroy the petrodollar peacocking over Ukraine. Once Russia forces the EU and other patrons to pay for Natural Gas in Euro or gold the petrodollar takes a massive hit. All of that inflation the US exports out into the global market returns back to the US with insane force, 10%+ years of inflation guaranteed. Biden is too incompetent to understand the massive self-own he is about to inflict on the US, Trump as a business major understood the oil business quite well and most of his antics during the 2017-2018 years were about slashing profitability of oil down to the bone because ISIS was accepting any currency for their oil.
