I cannot imagine how one diagnoses the problem of ‘Amazon has slashed pay and job standards to the bone and operates a system that amounts to indentured servitude for cheap labor’ and finds the solution to be to dehumanize, round up, and remove the same people the system is already exploiting.

It’s you who are missing the bigger picture. The problem is Amazon, collapsed labor laws and protections, and politicians who profit from both—not the working people they all abuse. By participating in the demonization of immigrant workers in vain hopes that it will raise wages (it absolutely will not, even if ICE deports thousands, the pool of willing contract labor is too large) you are playing directly into their hands, and fanning the flames of hate in the process.
