I think trying to translate thermodynamics into economics is a doomed quest.
Friedman's meme that inflation is always monetary, I think, is partly right and partly wrong, so wrong.
Demographics, for example, have a great deal to do to explain inflation.
We, like Europe, are in negative demographics. We can avoid disinflation, but I'll be interested to see how that all works.
I'm a boomer, like most on here. Our population, along with the after WWII/Korean unleash of demand, along with the Vietnam War unleashed inflation. But mostly, I suspect, it was the unleashed demand of an unheralded number of kids and the demand unleashed. Spending on Wars and stimulus also contributed, big time, but it was demand from all the families with kids.
We will see what happens in the next year, but I think post-COVID inflation is largely slayed, now.
As I told a couple yewts at the local pub complaining about prices, slow inflation is one thing. If you want Tall Paul giving you 16% interest rates, that will cause deflation and 10% unemployment. Be careful what you wish for. But I don't think most Americans understand what lowering prices means; I mean my Okie granddad in the Depression knew what that meant, but it was 30% unemployment in Oklahoma. He worked for the FDR works and sent the money back to Grandmother and my father, then pieced together 3 jobs to pay for them and his two sons after the works jobs trailed off (dams, roads and other projects). Unfortunately, my 3 year old uncle died in the cotton fields after having an appendicitis attack, so he only had to provide for one kid. But I am meandering about deflation here, which no-one takes seriously.
Off deflation, I think inflation rates are coming down to the normal and fear the danger is the Fed keeping interest too high too long, but I suspect the Fed will cut in September. Was it quick enough? Who knows?
