WE LITERALLY WATCHED IT IN REAL TIME. Covid caused supply chain issues, unaffected supply chains independently raised prices because people were willing to pay it. Trump was dumping $8T into the economy, business leaders also knew that. The supply chains started to clear up, but demand wasn't waning despite high prices. Throughout the entire thing anyone sitting on investor calls was hearing "highest profits in company history" over and over again.
Almost as if all that sociology about people behaving coherently without direct communication might have been on to something.
