It's oddly ominous reading about America's rise on the back of textile patents taken from England and Europe, then poaching of German physics talent and scientific talent from across the world. Germany was, by far, the pre-eminent power in theoretical physics at the turn of the 20th century, with Einstein, Heisenberg, Planck & Born about to be at the peak of their powers. Then the country decided to turn on intellect…
I don' think the situation is as dire as people think. Europe exported many technical people during the war years and one would be hard pressed to say they are backwards because they lost talent. Japan as well is not very friendly to labor migrants and they are at the forefront of science in technology despite their small population size relative to other geographies.
I could see Australia, New Zealand, or Canada similarly benefitting if the U.S. turns towards xenophobia & warmongering.
