It has always baffled me how the petite bourgeo seem to love cheap labor yet were openly racist to deport all the brown people without putting two and two together. Like, they couldnt connect that many immigrants were not competing against white people for jobs, but against other immigrants who didnt have much hope for something better given their circumstances.
Worse conditions for immigrants means the implicit threat of violence against immigrant workers is more effective. They're not trying to deport their own workforce, they're trying to pay them even less
