More like the new "America can't manufacture a grill scrubber" [1].
For those who haven't seen the video, YouTuber Destin Sandlin ("Smarter every day") tried to build a grill scrubber using 100% materials from the US and failed.
The claim he failed seems like hyperbole. He couldn't find an existing manufacturer for chainmail in the US but this is a fairly trivial and niche thing to create, and is more a reflection of how uncommon it is for people to need that specific type and size of chain mail than it is that the US is incapable of making it. The other part is from Costa Rica only bc he hasn't yet made the injection mold for it, like he did for the handle itself.
You have to separate the YouTube clickbait from the real learning content in there.
US manufacturing is expensive because wages are high, but also because we focus on the high end work that pays more . Even the small machine shops I used 10 years ago for small scale production runs are no longer interested in doing any small batch work. They have more contract work from big companies than they can handle, and the big companies pay more and have higher order quantities.
If you’re a shop or a factory in the US you’re never going to take some small orders for a grill brush from some YouTuber who doesn’t have any expertise in marketing grill brushes. Everyone is going to turn that order down because there’s no money or future in it, but there’s plenty of better work that pays better from companies who want to keep using your services in the future.
