I can understand the tensions from the housing crisis, and I can also sympathise with not having a lot of personal sympathy for the Americans moving right now, who most likely won't be refugees as such, but just people with the financial privilege and ability to choose where to emigrate.
But long-term, depending on how shitty the shit-show will get, there might be tent cities for persecuted Americans in the future, both for you and for us here in the EU (and, ironically, in Mexico, of course). You can say that you don't like it, and you have every right to - but at least in my eyes, it's an international duty to human rights when that point comes, and I, personally, won't give a shit what people feel, then. The international community will have to take them in unless we want to follow the international trend of fascism and say "empathy is the problem" like Elon. (Even though I actually don't think this would be about empathy, it'd be about upholding what remains of international standards, duties, laws and human rights, eventually with force if necessary)
