But what do we produce? If we produce more than we ever have, I want to know what it is and where it is, because I can't find any of it.
We do a lot of final assembly here in the States. I live not far from New Holland Agriculture, Sikorsky's civil aviation plant, Hershey Foods, M&M Mars, Dart Container (plastic lids), Giorgio Foods (they own the majority of the US mushroom industry), etc.
A LOT of stuff is sourced internationally. But final QA, assembly, etc are done stateside. Every time that gets outsourced, bad things tend to happen. Add in automation, efficiency improvements and often overworking employees, you need a lot less people.
There's reasons why stuff gets sourced so often. For smaller companies, because they get cheaper components and weed out the really bad parts or vendors by trial and error. Bigger companies, combination of inventory tax (hugely shapes procurement/manufacturer processes), international "free trade" agreements (sigh), favor-trading with governments, etc. If you sat through one trade commission run by the Department of State, you'd swear State is run by anti-American fanatics. Because it probably is. I had to leave after 5, 10 minutes. I hear the old Global Logistics guy I knew lasted an incredible 20, 30 minutes. And DIDN'T gut any State employee. Dude was hardcore.
America makes a LOT of stuff, and we're getting really good at it. Just with less and less people.
