Immigration is the symptom of synchronized global collapse ... expect more of it, and not just across national boundaries ... believe me, I live in Seattle, and this "liberal paradise" is constantly complaining about "homeless people from other places", which is pretty much the definition of an immigrant or refugee. Whatever faux compassion your article demonstrates is nothing compared to the cascading failure of human society, and the coming chaos - which will mean more people displaced, more towns and cities putting up their own "walls". Seattle's walls against the homeless? - metal spikes, bike racks where they don't belong, construction shielding, etc. ... after this comes the "camps".
