I think most textile factories in Western countries are not slave camps, precisely because we regulate labor.
Sure, that's why 99% of clothes are made offshore, but if we had something like tariffs on those (or requirements to prove that the actual factory adheres to labor and environmental standards), maybe more would be made "at home"? Similarly: Chinese cars undercutting US/German ones.
Most textile factories in the US are for bespoke items in small batches, not mass production commodity clothing
I mean there was just a video a couple of months ago of the giant room of sewing workers with cameras strapped to their faces capturing their hand movement so they could be automated
