The real thing is " How can an economy recover this fast ?" , We are not even that good with the vaccination part. Yes there are some vaccinations in the trial but they are still getting perfected.
As far as I know , US is depending upon other countries to help them out.
At its lowest point in April, the Back-to-Normal Index, which is comprised of 37 economic indicators, estimated the US economy was operating at about 59% of where it had been before the pandemic in early March
The situation improved a little but then fell as the schools and some shops started reopening and the cases begin to climb high.
As coronavirus cases surged in some places, states backtracked on reopening plans. For the last three months, the index shows the economy has largely gone sideways. It reached a post-pandemic high of 80% over Labor Day weekend before slumping again to 76%
It is not normal for sure and in the upcoming future I do believe that it will still take some time to stabilize, yes the president will try to pump some air in the balloon that is going to burst anytime soon , but I do believe he has been doing that since the pandemic begin.
What you said is too good to be true , I believe it will still take a lot of time , like a year or so.
