He was already traveling the world and giving lectures well before the rise of the Nazis, and he "simply" didn't return to Germany when they were in power. I can't speak for him, but I would assume he would consider himself as having had a good life with ample opportunities. The Nazis simply didn't even have a chance to persecute him, if anything the FBI made a huge dossier on him for his socialist views, though even that wasn't really persecution of the kind you ascribe to him by mere association. He had plenty opportunities, he wasn't born poor and certainly not Eastern European. I can't even begin to guess where you have any of that from, but it's not from the actual life of the actual person. And if that's the only reason you think the article is mistaken, then you don't have a (valid) reason.
Which makes the narrative that the lack of success in other groups is entirely grounded in lack of opportunity due to discrimination, rather shaky.
I often fear when researchers like the NYT author start conditioning on unchangeable characteristics like ethnicity and gender. It invariably implies a villain based on unchangeable characteristics like ethnicity and gender.
The classification of "Jews" has been the most innovative. Should we start making laws conditioned on someone being a Jew so that's non jews can become more innovative ? Does this not sound like a bad idea? (I am trying to dodge godwins law)
Also, educated richer Eastern European Jews tended to leave Eastern Europe way more then poor Jews who were numerous.
