I remember when it was the German economy in 60's to the mid 70's that would swamp the USA and the world! Than it was the Japanese Mid 70's to 90's, than it was the Chinese, etc. However the USA always seems to adjust and keep its steady growth over time. Now we see that the old saw about, "the US economy gets a cold and the world economy gets pneumonia is still true. Yes, we are the world's largest importer of goods, and we are the world's largest exporter of goods. Americans are pragmatic and like a challenge. Something tells me we have not seen it all, the best is yet to come!
