We’re wandering off topic, but I’m finding this interesting. America was the industrial might and it would seem to make sense, especially early on, that it was quicker and more efficient to recycle metals for munitions and equipment than to produce it raw. No doubt that scrap drives and other activities, like buying victory bonds and etc, had the additional merit of getting everyone involved. Hearing about the waste would have appalled my parents however, who went without a lot of things to be sure the troops were well supplied.
Cheers,
