1) Size of population, education and language are better explainers of the effect than any of these stereotypes or anecdata people bring up
2) These anecdata are generally biased negatively. Note the lack of positive (though equally bullshit) explainers like "they're just smarter and work harder than white people". This negative tilt is socially acceptable for Indians, but has become socially not acceptable for Jews. I don't particularly care either way as long as people call out the bias when they see it.
Implicit in all of this is how we as humans ascribe characteristics to our own groups vs. other groups, e.g. my asshole white boss is just an asshole, but my asshole Indian boss is an asshole because she's Indian.
Or as an Indian, my white co-workers is entitled and lazy because he's white etc. etc.
I think you’re right that people wouldn’t make the same comments about Jews and to me that’s an indication that Jews are more protected than they should be. Let’s all ask questions and let the truth come out. Better that than pretending that people don’t have in-group motives and waiting to see what happens when we’re not looking.
The moral of WW2 wasn’t “don’t persecute Jews”, it was “don’t be afraid to question those who are resisting being questioned”.
