If anything, this should have put another big dent in experts' expertise, meaning if they knew what they were getting us into with their decisions (after all, they're experts) and they choose this high inflation route nonetheless.

Sure, there is never a need to be an expert to claim knowing more than them.

Also, I'm not completely convinced that it's exclusively related to the Covid lockdowns in Europe. For instance, many companies were very quick to restart (or were not even stopped) in Europe, but struggle with the IC shortage... which is not coming from Europe, is it?

That increased money supply was at first not really felt because of the decreased money velocity caused by lockdowns and restrictions, but once things started getting back to “normal” in terms of lockdowns and travel restrictions and all that then money velocity got back closer to its pre-covid levels, and coupled with that increased money supply left us in the current situation.

Of course, the increased money supply is not the only explanation, there’s also the war in Ukraine which has put a tremendous pressure on energy prices, plus the supply crisis, but imo it’s still one of the main causes of what we’re going right now.
