You raise very valid points, but the way you address them has a very different ring to it than "the big elephant in the room is...", which is a pretty blatant a dog-whistle for "the problem is dumb foreigners". Now, I do wish to give the GP the benefit of doubt, but the expression is problematic regardless of intent. My comment was more of a response that implied dog-whistle. Admittedly, it was a bit reactionary because of my own personal experiences surrounding these issues, and the ease of which I have seen people blame things on foreigners without even a hint of self-reflection. But as you mention: the paper suggests these issues are not caused by immigration.
