The system that we had up until the late 1800s had a natural rate limiter in that the technology of the time made international travel so time consuming and expensive that immigration was simply an impossible pipe dream for the vast majority. It was also limited in impact on the native population because there were no welfare programs of any kind at the time, so an immigrant was never an expense item on the budget.

It may be your personal opinion that we should have the open borders policy you describe, and you are perfectly entitled to that, but here is mine. Your idea is borderline insane. Putting bleeding hearts in charge, who will allow things like this out of some compulsion that fairness demands we have the same immigration policy now as we did in the 1800s, is national suicide. I will continue to vote for anyone besides your side, even right wingers that I find repulsive, because I fear that someone on the left who lacks fundamental self preservation instincts will put in place policies like the ones you support.

1800s? We had actual open borders with the rest of the Americas until, like, the 1950s.

Farmers at the time were super-worried about the shift, since they already relied heavily on immigrant labor. Their concerns didn't manifest as major problems for them mostly because until very-recently enforcement was (pretty much intentionally) half-assed, such that the border remained de facto kinda open for immigrant farm labor (even, and especially, the illegal kind).

Now that situation's arguably not good for a bunch of reasons, but we've never had a strongly-enforced border, and in fact didn't regulate Western hemisphere immigration to any meaningful degree within living memory. Changing that to a highly-selective system with strong enforcement of immigration laws to keep out a large majority of prospective illegal immigrants would be a totally novel approach to US immigration. (Good or bad, either way, you can't really appeal to US history in its defense, and "without it the country will be destroyed by immigration!" demands an answer for why that didn't already happen, to remain a viable point)

> national suicide

Why do you think that? The same thing was said about the Chinese, Italians, Polish, etc... when they all came here. Instead they helped make the country what it is today.

I also don't see anyone arguing for open borders, but straight forward paths for people to legally immigrate.

What do they say, "quantity has a quality all its own"?

I don't really have a strong opinion either way on it, but I think your question was addressed by the natural rate limiter mentioned in the comment you were replying to.

Just like I was happy to have a free blog without a robots.txt 5 years ago, but now with the AI crawler and other traffic I'm looking at using Cloudflare "are you a human" blocks or whatever.

No, I don't advocate for open borders. I'm fine with keeping out criminals, people who don't value our democratic system, or people who aren't interested in being productive members of society (e.g., NEETs - people not either working or getting educated).

> Your idea is borderline insane. ... someone on the left who lacks fundamental self preservation instincts ...

Huh. Well, checking, checking... I don't feel insane. I'm feeling pretty calm, rational, and evidence-driven.

The two big risks I see from large-scale immigration is this: - people who don't agree with liberal secular democracy. E.g., religious fanatics who want to enact a theocracy. That's all good; I'm fine with screening those out. - economic damage. But here, again, the economic data shows that immigration distinctly benefits the US, mostly through economies of scale, but also partly through higher-than-average rates of college attendance and entrepreneurship in 1st- and 2nd-generation immigrants, leading to higher earnings and innovation.

There definitely are also localized *negative* impacts from immigration, particularly for overwhelmed healthcare and education systems. These do not outweigh the national net benefits - meaning, the US still benefits as a whole - but I can understand that people living in those areas or culturally affiliated with them would be anti-immigration. But these are problems we could very much tackle if we wanted to: the federal government has more than enough resources to help these locales, while still getting the long-term and nation-wide benefits from increased immigration.

So: no, I flatly deny that I'm not concerned with self-preservation. Yes, I care about compassion and fairness, but it's quite reasonable to ask that fairness and compassion be balanced with self-preservation. And yet - even after considering self-preservation, we still benefit from increased immigration.
