It'll take a while. Harvard's current endowment is over $53 billion. While I wouldn't discourage philanthropists from attempting to use the power of the purse here (having taken all three of the universities in my will, out), that becomes more difficult when ideologues have stolen the entire purse for themselves, and consider their institutions ground gained in a decades-long military campaign often dubbed the Long March Through The Institutions. That gain isn't to be reasoned away, it was gained by force, patience, connivance, and misdirection, and is likely only to be surrendered the same way. What passed in the 70's, for example, as an antiwar bias turned out to be prowar against existing society; what passed as anti-authoritarian turns out to be militantly pro-authoritarian in favor of the new orthodoxy. The masks have come off because they hold the ground.
Every revolution requires student passion, and the less critical those students are, the better for the revolutionaries. What passes as educational turns out to be anti-educational, the most visible signs being the outrageous cheapening of academic credentials, especially in the liberal arts, and the relentless attempts to degrade the STEM curricula as well. The donors supporting much of this haven't been private at all, they've been the public taxpayers even in nominally private institutions, and believe me, none of the recipients of this largesse has the slightest inclination either to acknowledge this or to inquire as to the intentions of the frequently critical involuntary sources whom they consider their inferiors.
Private schools’ obsessions about race (Exeter, for instance, setting a 50% “people of color” target for admissions before reviewing a simple applicant,) will also have an effect on academia at all levels. In many cases this because the white kids admitted will already be legacies, who traditionally underperform others.
That is to say, frankly, that the students going to the big schools are decreasingly chosen on intelligence and performance factors.
In the secondary school world, schools like McCallie in Tennessee, which is a diverse but decidedly not-Woke institution, are now welcoming some of the brightest kids in the country... Kids whose families eschew race-based admissions policies and kids of “inferior” (white, asian) races.
This is the first time we have seen people, when talking about high-performing students, talk about “Choate, Exeter, Harvard-Westlake, McCallie...”
It will be interesting to see how desirable Harvard grads are in 5 years.
