No western country conducts mass deportations, least of all of long-term residents.
The reason most advanced economies don't need mass deportations is because they enforce immigration laws more strictly for jobs and for schools --therefore they have fewer illegal immigrants (due to fewer incentives). On the other hand we allow more legal immigrants than all those other western economies --which is a good thing.
I'm okay if those same people just get back in line with everyone else, by the way. It may take a while, but take your turn like other legal immigrants.
PS. Latin American countries from time to time do conduct mass deportations, so it's a bit misleading to say none do. Even Angela Merkel said she'd deport upwards of 100k immigrants she first allowed in (thus legal).
Countries have many policies to keep people out. Do you think Mexico or Japan don't keep people out? They too have policies for who can enter their countries for what. It's normal. We're the outliers in terms of policy non enforcement compared to other nations.
