Many things that were once considered "common knowledge" turned out to be nothing of the sort. The idea you're espousing is a damaging one that reinforces the worst stereotypes about Jews.
I take pride in being extremely charitable and not toxic when discussing topics with people, but I find your accusation that I'm doing something damaging as incredibly rude and uncalled for.
The claim that Jews are over-represented in fields correlated with success, such as finance (once my field), journalism, and academic disciplines such as physics, is not damaging, even if it is wrong. How would the view that Jews tend to be successful be one of the 'worst stereotypes?'
It's strange to me that you're so unaware of Jewish success that a banal claim that Jews have a high representation in some fields has you shocked.
I took a few minutes to at least get a couple sources, but honestly if the idea that Jews are over-represented in fields like physics or journalism or economics (or ivy league universities) is new to you, then you haven't done a very good job paying attention in class.
You're changing the goal posts. You went from saying their representation is extremely high to over-representation. Over-representation is simply a higher percentage than their demographics in the US might imply. High representation implies that they hold majority or near majority of influence.
It's strange to me that you're so unaware of the anti-semitic tropes that portray a Jewish cabal controlling politics and media in the US. Perhaps you weren't paying attention in class...
