Or, crazy idea, we make life livable for the locals and then we incentivize them to have kids of their own? And before you say it, I'm an immigrant from the 3rd world myself. I'm not anti-immigratiom, but the birth rate talking point is a very poor one.

Not to mention how unsustainable it is anyways, what happens a few years down the line when the immigrants stop having kids? There isn't an infinite ocean of people you can import on a whim, and definitely not forever.

I don't get this argument. We skip over fixing the birthrate and instead rely on immigration. There's a whole bunch of reasons people give for why we can't fix it like costs, jobs, housing, etc. Ok, so then first wouldn't immigrants also have the same problem once they get here or do they have a way of bypassing our low birthrate somehow but then we were told we can't bypass it, it exists because of the costs, jobs. etc.

So the immigrants end up with the same birth rate and then we have to bring in more immigrants. So there would have to be a constant source of excess people somewhere else for this to be sustainable. So it gets to a point where I wonder if this is really the plan.
