I sympathize with your situation, and I'm not calling you a monster. But "I had no choice, I had people depending on me" is the exact reasoning that has enabled every atrocity carried out by ordinary people; it's the banality of evil.
None of the individual acts seem evil. Conducting a census isn't evil. Collating the data isn't evil. Arresting people with the wrong papers isn't necessarily evil. Driving a train isn't evil. Operating a switch isn't evil. Processing paperwork isn't evil.
Look what's proposed now: Adtech has the data, this would feed into ICE systems leading to arrests, flights are conducted, and people get put into prison camps like CECOT where they have no recourse and where people are already talking about forced labor.
So no, I'm not saying to these folks "you're literally causing Auschwitz". That's a famous Vernichtungslager, and that's not true yet.
But people getting locked up in Concentrationslager or Arbeitslager (like historically : Mittelbau-Dora, Flossenbürg, Mauthausen, and Monowitz). I think we're getting there.
I guess the question is: at which point do you decide maybe to wear extra layers or skip a meal instead? We're not there yet. The chain has many links. Eternal vigilance is needed to make sure they don't actually link up.
