They ran out of Jews.
There is a component to inflation that has been missed. The cost of production in the US has increasd enormously in the US since the 1970s. OSHA, EPA, NHTSA and all the other alphabet soup Federal agencies have added their regulations to the cost of doing business. Here’s one example: A company I worked for wanted to encapsulate (build a culvert over) 100 yards of a very small creek so that we could expand the storage yard. Two permits were required, one from the state and another from the Corpse of Engineers. Two environmetal professionals spent a whole month preparing the permit requests. Two engineers making $80k per year at one man-month of labor each and you can get the picture. That happens thousands of times every year across the US. The only recourse is for companies to pass that along to the client.
BTW “corpse” is not a typo, I do that on purpose.
