To be fair, other countries want US citizens even less than the US wants* immigrants.
Do people actually think that the US is alone in anti-immigration sentiment? Do they think it’s different because they’re American?
The US is the one with a giant monument to immigration, at whose feet is a plaque that reads:
Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore. Send these, the homeless, tempest-tossed to me, I lift my lamp beside the golden door!
And if they, of all people, are now against that, what makes Americans think anyone else will want them? It’s delusional.
Many countries shut down immigration to Americans in 2016, after the first round of trump’s policies, and they haven’t opened back up yet, partly because there was a solid chance of this happening again.
