Yep. And their action doesn't justify or excuse China's or vice versa. It's bad regardless who's doing it.

A lot of the immigrant labor has been at least slave-like for decades too. Under constant threat of deportation on their "employer's" whim. Fairly common for "employers" to take documented worker's documentation to hold them hostage. Reports of some farmers housing and working workers fenced-in, having them working under gunpoint. Some farmers have been caught buying and selling immigrants amongst each-other. I remember a report of a meatpacking plant calling ICE on its own employees to have them deported after they started asking for better treatment, then just hiring more immigrants to replace them. Hell, I even remember near where I grew up, you could see the shed-like shacks from the road on one farm where they kept the migrant workers; no electricity, didn't look like they had any running water either.

ie. American prison

Gearing up? El Salvador is taking them in already.
