The Nazis’ dismissal of Jewish scientists had a much greater negative impact on research output than did the wholesale destruction of buildings and equipment by allied bombers...
My guess is that your thesis is more accurate than Smith's. But I am going to go off at a bit of a tangent on the subject of emigration/immigration:
The only sane immigration policy for an rich society to adopt would have been to filter/select for the immigrants who could convincingly show a very positive identification with the values of the host society. (Immigration to19th/early 20thc. America was approximately that way....or am I romanticising?) They would not necessarily have had to be intellectually top notch....just keen to contribute. You could even make a case that the emigrant culture would benefit from off-loading some of its more culturally alienated citizens (although not a strong case I suspect).
I have said "would have been" deliberately because - in the US and much of Europe - that horse has long ago bolted in the wake of 'multiculturalism'. (For instance, any documentation produced by the UK National Health Service these days will convey some useless bit of information followed by several pages of translations of said information into upwards of 30 different languages because God forbid that they should feel the need to learn the language of their new home) Rant over. https://grahamcunningham.substack.com/
Convincing. It would be interesting to see a similar analysis looking at unskilled migration. Does it provide a benefit to the country of origin? In other words, are unskilled immigrants coming from the other end of the tail, or do they possess other valuable attributes (e.g. determination, persistence)?
Indian IT workers have not done anything for the US except lower wages for American IT workers who are eventually replaced by Indians. Filipino nurses have not benefited the US, it's just lowered wages and created Filipino enclaves all over the US further adding to the ethnic confusion that is the US today. These workers and now residents, send billions of dollars home in remittances that might benefit India and the Philippines, but is money lost permanently to the US. The importation of "skilled" workers who are too genetically different from the European majority in the US has been an unmitigated disaster.
“For example, the average intelligence of US college graduates has been trending downward over time because less and less intelligent people have been enrolling in college.” Fewer and fewer?
And is this even true? Or is the proportion if the intelligent population applying to college mostly stable, while the mediocre and ret*rded portions rising? Otherwise great article

This is automatically assuming that the research that was being done by Jewish scientists was useful. A large number of the Jews who were doing "research" in Germany were in the "soft sciences" and theoretical physics, neither of which are very useful. These "scientists" all fled to the United States and we can see the fruits of their labors today. Half of the young population doesn't know what sex they want to be, boys chasing boys and girls chasing girls, a scientifically illiterate population that takes shots that haven't been tested that thinks that carbon dioxide is a pollutant.
Germany lost the war because they couldn't match the manufacturing of the United States when it was at it's peak, much the same as the United States and Europe are losing the Ukraine war because they can't match the manufacturing might of Russia and China. If the Jewish scientists had stayed in Germany it would've had very little impact on the outcome of the war, there would've been more gender confusion and useless books about the big bang and discussions on whether the term "black hole" is racist or not.
