As a non-American who has to live in a world that's deeply affected by the schizophrenic convulsions of your current government, I hope you stay in the USA and work on fixing your mess.
That is an absolutely fascinating worldview. I don't know what country you're from and what pain and suffering you've been through that was caused by the US govt., but you've managed to get me to stop caring. Sparkling incompetence. While we're exchanging unenforceable opinions about what random people on the internet should do, you should go help your own country -- by leaving it.
The US is an extreme outlier in accepting migrants.
The current situation is effectively what the vast majority of countries already do.
Some go beyond that, and gun down people with machine guns at their border.
The idea that the US is not a country that belongs to its citizens, but some sort of abstract global entity that everyone in the world is entitled to is farcical, and it's coming to an end. The US owes absolutely nothing to non-US people.
If people don't like it that can go anywhere else (keeping in mind that other Western countries are starting to do the same) or, you know, stay in their own country? (Crazy, I know)
I’d be fine with America not wanting the world to feel “entitled to” it, if at the same time they’d stop feeling entitled to the rest of the world themselves.
Vietnam. Middle America. Afghanistan. Iraq. Greenland. Venezuela. Iran. Now Cuba.
