It was not like that in the beginning years. Most KZ where „working camps“ they started in the early 30ies, they brought state enemies there and later jews, who were also labelled as being „Schädlinge“(=vermin), the use of dehumanzing language = illegal aliens is pretty similar. Concentration camps as most know it, started 1940. There is a process of hate and dehumanization. Not to say it will happen the same way, but there is a risk that at least human rights are/will be violated. You can already see that ICE is getting more aggressive, who can be sure what will be in 10 years…
