They are conveniently white/white-passing and such can take advantage of that.
There has been a historical bias against anyone who is not WASP and this bias subsist to this day. And that's not restricted to jewish people or asians.
I have seen lots of disdain for some of my french coworkers despite their talent and value-add and overheard "banter" (behind their backs, mind you) that would have been unacceptable for any other minority.
So, as you see. This is not a matter of white/not-white/white-passing. It's clearly an issue with the cultural identity of the majority-minority of this country and multiple thick layers of biases that need to be scraped.
If you killed off the least successful 50% of white Americans, then white attendance at Harvard (presumably unaffected) would go up relative to the (now halved) white proportion of America.
I don't like the label "asian" and "white", they make very complex mosaic look like monoliths.
The US Census Bureau's labels (White Caucasian, Jewish, Hispanic, etc.) is singular in that its the stupidest and most harmful nomenclature ever created, even contextualized with US history.
It has introduced conceptual confusion at every level and is all the more devastating as it is the standard mental model people use to reason about these issues.
It is setting back the US by at least a few decades, the time people realize its inaccurate, and discard it as what it is: trash.
