I think the WASPs fell from power decades ago. It's almost inexcusable that they could have any power in a hyper race conscious society. I think they are kind of viewed as an archvillain in this country in some sense. As a result, I don't think the WASPs are still in control there. I think the sensibilities you mentioned to get in are not WASPy, but reflect the new elite.
It's likely that if explicit racial discrimination is taking place, it's more for pragmatism. The Black and Hispanic student body % shall not be reduced. The country is still ~60% white but the white student body % has been reduced dramatically over the last decade. That trend will continue but it's not pragmatic to do it all at once. Nothing like the scale of immigration in the US has happened ever in history. The top 0.01% of populations > 1B in Asia can move to the US and within one generation achieve elite status and that's still more than enough to fill every spot at Harvard.
Meanwhile, Harvard remains a seat of major power in places like DC and corporations and law schools and science. There are far more elites on the planet than there are seats at Harvard so it's likely to cause major tension in the future and my best guess is Harvard is being pragmatic and slowly reducing the white population as it increases the Asian %. Who knows what the Jews do? Maybe claim victim status and get a guaranteed seat. Since Harvard is a gateway to power, it's likely this is going to be a source of major tension in the future.
