They want the “migrant worker” paeudo-slavery thing they do in other parts of the world, where laborers are a separate class of worker which don’t have rights. And by dont have rights, I don’t mean like the current state of affairs where the constitution still applies to undocumented immigrants. They want to codify a separate class of non-rights into law for these people so they can never sue their employer, don’t have a minimum wage, can be charged for housing, etc
