- "lying in wait" for the director of college counseling, in the vestibule, parking lot, or outside the office door,
- requesting student records for other people's kids.

Many private-school kids feel that there is a separate set of rules for the children of huge donors. And in my opinion, they’re absolutely right... It’s not unreasonable for a big donor to expect preferential treatment for his or her child. And it’s not unusual for him to get it.

Jim Best's plan of Summer 2020, to make Dalton a " visibly, vocally, structurally anti-racist institution"
Faculty and staff plan of Summer 2020:
"-Half of all donations would have to be contributed to New York public schools if Dalton’s demographics did not match the city’s by 2025;
- the school would have to employ a total of 12 diversity officers (roughly one for every 100 students);
- all students would be required to take classes on Black liberation;
- all adults at the school, including parent volunteers, would be required to complete annual anti-racist training.
- Tracked courses would have to be eliminated if Black students did not reach full parity by 2023."

The parents are consumers of a luxury product. If they are unhappy, they won’t just write anonymous letters. They’ll let the school know the old-fashioned way: by cutting down on their donations. Money is how rich people express their deepest feelings.
