But Pizzashill assured me the two were completely unrelated?

For example.

2. The combined effects of increased demand for durables and shortages caused by supply-chain disruptions were the main source of inflation in the second quarter of 2021. Both the direct and indirect effects of those supply-chain problems remained substantial through the end of 2022.

3. Tight labor-market conditions, one of the main concerns of the early critics of U.S fiscal and monetary policy, contributed only slightly to inflation. In fact, the tight labor market affected the economy negatively in 2020 and early 2021. Since then, however, the traditional Phillips-curve effect has begun to reemerge, with the high vacancy-to-unemployment ratio becoming an increasingly important factor in the high inflation rates.

Bernanke and Blanchard argue that the critics' concerns of higher inflation were correct. But the sources of the high inflation differed from those the critics had anticipated. The authors conclude that price shocks in product markets were the leading cause of the initial rise in inflation. However, as labor markets began to overheat in 2022, with unsustainable employment increases, a high ratio of job openings to unemployed workers, and low levels of quits, labor market tightness increasingly became the main cause of the persistently high inflation rates.
