Meat packing, farming & agriculture in North America is run entirely off the backs of immigrants, poor people and people of colour. People don’t choose these jobs, they take them out of necessity. This is just a fact, and a weird hill to die on.
If you want to rebut the argument that this is unique to meat, look no further than fruit picking in the US. It’s less risk of maiming and disgusting, but still dangerous and exploitative.
