What’s the best explanation for the US having so much more real economic growth without more inflation than the other countries in the G7?

The best explanation for the US having more real economic growth without more inflation than the other countries in the G7 is that the US has seen[1] better-than-expected consumer spending, relatively low consumer debt burdens[1], remnants of pandemic stimulus and savings[1], and a strong trajectory for inflation. This has fueled a solid pace of growth[1] and kept inflation in check.
