Yes it's obligatory. Stagflation is not a new phenomenon. It's started around the 1970s. Which led to the rise of monetarist and the decline in Keynesianism.
But of course no one dare mention, that the west support in the Yom Kippur war, and the subsequent turning off the oil tap by the Arabs would have anything to do with it? Plus the fact tricky Dicky Nixon abandoning the gold standard.
All these leads to cost-push and import-push inflation and stagnant economic growth, which is hence the name "stagnant inflation" (stagflation).
Joy, I remember queuing for petrol in patents car. I thought we will be spending half our lives queuing!
I suspect it could happen again as oil prices and other commodity prices rise.
US oil companies are dead and Biden is only going to hurt them more. US will have to import oil again.
US will keep printing money and the stagflation cycle begins.
