Cold Spring Shops posted this video from 1944 about how steel is made. It’s about 10 minutes long, and only the last minute or so is required for class. But, if you’re curious why steel production is mostly done in other countries, the first 9 minutes should make it clear why you wouldn’t want this sort of work.
Starting at the 9:07 mark though, the narrator makes a bunch of points that sound like they came out of Monday’s discussion of Ethan’s question in the Quodlibet on Canvas: at that time there seemed like there were few coordination problems, but people could remember when they’d occured recently, and the idea was dawning that those coordination problems were correlated geographically.
BTW: the volume is very low in the source. Not much you can do about that.
