If inflation is low and controlled it means the supply of money matches the demand for money which is usually associated with value creation in the economy. The fact that EU was doing well inflationwise despite having looser monetary policy than US means that Eurozone economy was doing better in that period than US and global economy. Of course in relative terms.
My entire point is that the monetary policy in the Eurozone has been considerably looser between 2014 and 2020 and comparable after that.

So the ECB "printed" considerable more if measured that way, prior to 2020 at least and they were relatively "fine" inflation wise.
