In my view, we can never not have a shortage of talent when it comes to scientific disciplines - at any pricepoint. The beauty of bringing more researchers to the country is that they eventually help create as many or more jobs than they "take".
What leads you to say that? I'd take the counterpoint. Much of what passes for "science" these days is glorified p-hacking for conference proceeding churn and sweatshop adjunct work to pump out a minimum amount of monetizable IP to underwrite an ever bloating university administration complex. It seems closer to scientism than to science for me. And I think that is the natural result of intellectual pursuit being diluted into a commodity.
On the comment regarding "p-hacking". I think that is a separate issue altogether and irrelevant to the discussion. Universities have essentially become businesses and they push scientists to "publish or perish". If anything, it is a case for democratizing science even more.
I think you meant to say there will never be an excess of talent? (If I’m reading your comment correctly)
