We export LOTS, including the bulk of popular culture around the world. It isn't a tangible good, like a car or a TV, but it's still a product, and it's responsible for trillions in revenue. Until MAGA, our R&D for a lot of industries had been at or near the top. Nations around the world send their best students to American universities for their educations. We may not manufacture much, but the idea that we contribute nothing is flatly stupid.

The American economy is entirely woven into the world economy. If it all collapsed, the world would NOT be fine, for the better part of a century, at least.
