The US has by far the largest trade deficit in the world. It's a net consumer, because it can print dollars. It is not remotely the most powerful productive economy on a per-capita basis.
Compared to small, rich city-states and oil-rich Middle Eastern countries, sure. But in any more apples-to-apples comparison — the EU, China, India, Brazil - the US is in the lead by a lot.
It's certainly an accomplishment to achieve a highly productive per capita economy, but I don't think it's quite the slight on the US when the four countries with higher productivity per capita range in size from 0.3% to 2.8% of US GDP. Achieving productivity per capita at scale is hard.
