It will help would-be immigrants understand that the US does not want them and that it would be a mistake to invest time and energy trying to build a future in a country that hates them and can nuke their lives at the drop of a hat. It will help other countries that are not the US retain their talent and build up their own industries. A greater diversity in distribution of talent and industry across the world is a more resilient system.

They mean good for everyone NOT the US. Because now say, Germany or France, or where ever, come off as a better place to immigrate, so other countries can build stronger more competitice businesses.

This move, like everything the MAGA administration does, will only weaken the US.

Even better for other countries, anyone the US produces who isn't a raging idiot, also are more likely to want to immigrate from the US.

It could be good for anyone country that's not the US (despite our hubris, we're not actually the center of the universe). But for the US, a country built on immigrants ands immigration, probably not so much. We fucked around, we found out.

Well, we're continuing to find out. We haven't exactly scraped rocked bottom yet.

I think the parent is saying it's good because immigrants will go elsewhere and the US will continue to decline. Which will be good for humanity.

I think it's sarcasm
