If the quality of life was unsustainable without immigration, what makes it sustainable with?
Current immigrants come from countries with high population growth. When their population growth slows down, will they get their immigrants too?

Think of it like (internal) trade, it's a win-win. I've been reading about Brexit recently. It's super easy to convince uninformed UK voters that "look the EU is benefiting from trade with us, so if we stop trade we can take all their benefit and keep all our benefit" ... That's not how it works. In the real world it's like Taiwan specializes at chips, China specializes at solar, India specializes at medicines, etc everyone brings something unique to the table and we ALL benefit from working together. It takes a lot of balls to leave your original country family/friends/etc. Immigrants are usually high quality people, it's best to just let them work.

1) How is that your problem? Have you ever been worried about China not having enough immigrants before? The US is extremely well-positioned to win this one.
2) Yes there will be increased competition for immigrants, but it's really not a bad thing. I'd love it if the UK was politically stable so I could just move over since the US keeps trying to elect Hitler.
