@Baldimo,
I don't know that I pushed for a UBI anywhere, but I'm open to the idea.
I see that as being a 2040 and beyond possible solution though; automation won't hit us that quickly. And automation won't eliminate ALL jobs. Immigration and automation won't be turned on 100% at the same time, so like everything this big, it will take decades.
More people means more housing, means more grocery stores, means more restaurants, means more schools, means more barbershops, means more of everything that societies expect.
Automation makes the immigration "problem" even easier to manage though. Everything you end up automating become cheaper (otherwise, why automate). If food become cheaper or if robots start building our houses, etc then it makes it easier to live on less income. It means the "living wage" goes further. It means that a UBI would go further.
Your other points? Like mandating that they speak English? I didn't think they were debatable topics. You were stating your opinion or preference. I disagree and didn't have anything else to add to try to convince you. I think we should bring in just about anyone who wants to come, skilled, unskilled alike. Screen for criminals, give them green cards or whatever visas they need to live and build a life here. Unskilled workers will find jobs, they will pay into social security, they will buy food, they will live in houses, they will be consumers and tax payers...their kids even more so.
If you want to keep government benefits away from them for a period of time (outside of school for their children) then I don't know that I'd have much of a problem with that. I think it's a drop in the bucket, but if that's what it takes to get them legally here, it's a compromise I'd be willing to make.
