Who, funnily enough, will probably be the largest impacted by such things as locking down H1Bs.

Old and still accessible beats inaccessible. BTW the source of the USAs demographic resistance to aging has been the sheer fact it was that immigration melting pot of bringing in young talent to offset its local aging population. A few decades of this path and the US can be just as dismissed as Japan who have taken this path decades in advance.

All countries will end up like Japan, it’s just time (explained in the links I cited). Some countries are likely willing to eat some economic gains out of other preferences. That’s a choice. It’s not all “line goes up.”

India’s total fertility rate is already 1.9, below 2.1 replacement rate. Its demographic dividend (and any potential capital investment opportunities) is already on borrowed time. So capital would rotate and reallocate there, while there is still time, regardless.

Per slide 8 of your second link: Except Africa and half of Asia who will still be above replacement rate for the remainder of our natural lives.

Per exhibit 5 of your first link: The US still to be as bad as Europe and Japan you disparage as "old" and that is based on 2024 analyses. A few more years of these events if sustained will drop that further.

And per Exhibit 1 of that same link, sure India will be at 1.9. And the US was at 1.6 two years ago, which is worse.
