I think most people here would say "jobs".

While it's true the US is a massive producer, it focuses on automation, which means more productivity per job.

And this is the crux of it all. US factory jobs weren't Los "overseas" as much as they were lost to machines. Each production line needs fewer and fewer workers.

Yes, you can cherry-pick examples (software jobs going to India or coal mines closing etc) but even mines use much less labor today per ton of say coal than they did 50 years ago.

So really, I think, the sense is that good blue-collar union jobs are what's dwindling. It's less about raw output and more about job losses.
