the ironic thing is that the US did tons of direct check-type helicopter money and yet our growth is healthier and more robust than anyone else in the world (and the dollar has also outperformed).

given other countries did not undergo similar fiscal programs and have faced similar levels of inflation, i would argue that the larger component of inflation was the sudden global start-stop supply-chain shock from the pandemic rather than purely excess demand from the too-large fiscal programs. and i do not consider that shock to be self-inflicted (tho the excessive fiscal spending certainly was).
