There's a lot of adjectives - almost all printable - I'd go through with reference to Soros before I'd remember that his ancestry is Jewish. One of the adjectives that comes to my mind before "Jewish" is "Hungarian". Another is "convicted criminal" - a French insider trading conviction.
I was not aware that Yellen is Jewish - religion or ancestry.
I've never heard of Lloyd Blankfein. If I had and were to speculate as to his ancestry based on his family name, my guess would be Jewish. But I don't attach any more racial-moral significance to a Jewish person working in the banking industry than I do to a Japanese, Taiwan-Chinese, mainland-Chinese, or Indian working in Tech.
