YYA> Germany in the 1920’s Jews had more rights and opportunities than anywhere else in Europe.
And in US. Fritz Haber (German Noble winner for inventing fertilizer process and saving billions of lives, and forgotten because he invented poison gas for Germany and killed thousands) visited Atlantis city in c. 1910 and was shocked to see “no dogs and Jews” signs – even when he was told this does not affect him personally as a civilized Jew. He said that nothing like that could happen in Germany …
But another question – we have Gemora from Bavel, Rambam from Muslim Spain, Shulchan Aruch from Poland, Litvaks and Chabad from Russian empire. What do we have form NYC? R Avigdor Miller, Chaim Berlin, YU? Jewish bankers and lawyers?
One sefer muses that Jews were sent to different countries to pick up different middos – scholastics from Germany, survival skills from Russians, etc. For America, he chose “scale” – from McDonalds chain to large yeshivos. Not really a middah. but a method. and “large” is not same as “great”. Maybe general uniform education creates some quality like synchronized swimming does (I am told).
