Given that a measurable part of the “eliteness” of those formerly respected universities was due to the Jewish students, when they leave, the ivy league becomes more and more like the poison ivy league. Oh, and the reason that the Jews do so well is that their families have two things lacking with the left: discipline and morals. (This comes from a person raised as Catholic - back when the Pope was also Catholic.)
“their families have two things lacking with the left: discipline and morals”
It is more than that.
Many Jewish families are fanatical about their kids having high achievement in school—many Chinese families are the same.
Many Jewish families are also mini debating societies—not just about trivial day to day stuff but a wide range of issues so the kids get exposed early to the sum of human knowledge—and many learn to enjoy the “give and take” on those topics. That creates a greater motivation to learn so they can actively participate in those discussions.
It is not just politics that is discussed—it is philosophy/religion, the span of human history, cultures of foreign lands, the arts and humanities etc.
If learning can be both “fun” and rewarding (on a psychological level) the battle is won.
