The problem you run into here is that each time there was a sufficiently large threshold of immigration growth, the government did respond by sharply curbing immigration. So we don't really know how things would have turned out without that. And that was also during times of significantly higher fertility rates, so higher rates of immigration would have had a relatively smaller impact on society. There were also much higher rates of self employment (a quick search suggests ~50% in 1900), so there'd be less concern over the job market and instead even a benefit to be gained from more consumers and even laborers - the same reasons that corporations tend to support immigration in contemporary times.

So in modern times the situation is quite a bit more different and relatively unprecedented, at least if we continue along with anything like the former status quo. But I'd wager that the former status quo is probably dead, even after the current administration leaves office. The DNC is showing good predict market rates for a win in 2028 and I'd wager that they'll run on a much more moderate platform for immigration, far away from both Trump and Biden.
