I would agree, TFA says much more about USA industrial organization than it does about butchering animals. After all, humans have butchered animals for many millennia. We recently had a cow slaughtered by local Mennonites. I can report that none of these awful things were going on there. There might be some "child labor", if one's definition of "child" is more expansive than that of the Mennonites. Still, they have none of these nightmare machines and anyway not even a Mennonite would make his own kids try to clean one while it was still running.
