I'm guessing some people already know this, but I was under the mistaken belief that the U.S. had already lost this crown some time ago. It seemed to me almost everyone thought everything is made in China and we produce little here. Turns out I was mistaken and even with far less population we still out-produce China; although, apparently, not for long.

Sorry, it seems I can't link this story from the Financial Times. If you look up the story heading in Google, though, you'll find it and be able to read it without subscription.
I found another, though shorter story on this.
