Easy to explan  

First,  Biden dumped 1.9 trillion dollars into the economy.  1.9 trillion dollars that was a recovery program for a issue that the US was already recovering from.  The GDP from Trumps last quarter was a plus 38%.  The economy was already in recovery.  No recovery program was needed.  But, Biden just dumped a massive amount of money, starting inflation.

The choice between an economic contraction, inflationary pressures and job losses is easy and has been made many times. "Easy" does not mean without consequences, but a short sharp contraction and the corrective currency changes resulting in inflation is, in my opinion, better than the late '70s early 80s stagflation.
