Ace, I thought the above article/link would answer your question a lot nicer than I would if this is actually a genuine inquiry on your part.
Hint: It has jack shit to do with Biden like the misinformed like to claim. Or maybe Biden is also the president in Argentina too. Comprende?

Inflation kicked off earlier in the USA than it did in other places, because of Biden's $1.9 trillion American Rescue Plan (ARP). From your HBR article, "On the demand side, many countries funneled large sums of money to households and companies during the pandemic, to ensure that they could manage lockdowns and layoffs. That increased the money supply and may have contributed to inflation." As Larry Summers and our own Texas Contrarian pointed out, the ARP way overdid that. Thanks for the article btw, it was an interesting read.
Anyway, in June, 2021, YoY CPI inflation in the USA was 5.4%, compared to 1.9% in the EU.
The Fed didn't help matters much either. The Fed Funds rate was 1% going into June, 2021, way below inflation. It should have been tightening in reaction to the massive fiscal stimulus from the ARP.
About your other article, I visited the central bank of Argentina museum in Buenos Aires. Inflation there has been a perennial problem. It was ridiculous. They were always doing something like reverse splits for the currency. You'd trade in your million peso banknotes for one peso banknotes. The governments weren't willing to jack up interest rates and stop printing money, because they figured they'd lose the next election. Yeah, the solution isn't easy. We suffered through a recession, reduced GDP growth, and high unemployment between about 1980 and 1988 here in the USA when Volcker jacked up interest rates. But it was well worth it, to keep from going the same way as Argentina.
