In theory, not in practice. If they are "controlled by the government" then illegal immigrants should be deported. What is happening is that a lot of people come illegally, often against wishes of local population. That's why it's "mass".
Speaking of EU (as Musk is often criticized for expressing his views on EU countries): majority of people support some level of remigration. Vast majority supports stopping illegal migration. Big majority is against migration from Islamic countries. Instead we get all of it at mass scale against wishes of the people. Musk is with the majority here but against ruling elite. His view is well in the middle of what people in EU support.
I believe that this is a false narrative that's being pushed as vote attractant.
> Vast majority supports stopping illegal migration
Yeah, well, it's illegal, so even the establishment is against it. From the, admittedly minimal, sources I hear from it's way overblown by politicians and their supportive media outlets as an easy vote capturing exercise playing on basic human tribalism and fear.
That kind of attempt to redefine what migration is, is classic manipulation of the narrative to try and appear more centrist.
Looks like it works pretty well too.
Migration levels are controlled by government and are generally based on the needs of the society being governed. I thought the rules had always been pretty strict on getting into most western countries.
