Most peeps looking at this situation ignore (or are unaware) of the first level issue. It's it demand side or is it supply side. Demand side can rebalance eventually and is less harmful. Supply side means everyone is now poorer and it's more painful on top of also including a unequal distribution of that pain.
The 1970s was supply side - driven most significantly by the fallout of the oil shocks.
> The inflation is a consequence of a mistake that has already been made by the Fed - overly expansionary monetary policy since 2021
However you miss the next important level of distinction in inflation. Inflation in what? Basic goods and services or investments/ assets?
People have been claiming that the Fed's policy (and QE) would kick off horrible inflation in goods and services now every year since 2009 and it never happened. When did goods and services inflation start? During the supply side shutdowns of Covid when hundreds of economies worldwide began producing less due to people remaining home, getting sick, retiring early, dying and factories and shops closing.
Then goods and services inflation kicked into high gear with yet again the oil spike. Oil price doubled in roughly 18 months, peaking earlier this year. And yet again we see goods and services inflation.
The inflation that's hitting common families is (as usual) supply driven.
Now is you're a crypto investor, or a real estate investor, or looking to buy a house, or own stocks, then yes you have legit complaint about the demand driven asset bubble and subsequent popping due to the Fed's policy of cheap money. But the reason trips to the grocery store, filing up a tank, and every day costs are more expensive now is due to supply side.
