And then they reversed in 2019 when the stock market started slowing down and Trump freaked out and pressured them to keep the unsustainable growth going, leaving us collectively in a weaker position to respond to the covid crisis.
The tax cuts that cost us $1 Trillion/year is the bigger issue at that timeframe.
The 2019 reversal was... well timed for the wrong reasons. Every economist will tell you that these Fed-moves take over a year (!!!) to kick into effect. Since COVID19 occurred in Nov 2019 into March 2020, the 2019 reversal was actually perfectly timed.
For all the wrong reasons mind you, but... we kinda got lucky there.
