The tuition is on the high end - must be prestigious schools from east/west coast. I remember that Donald Trump younger daughter 's private school is below 50k annually.
Cranbrook where Mitt Romney is from charges $31k and $42.6k for high school day students and boarding ones respectively. I would think that the majority of the families consist of parents with equity compensation, big time lawyers/doctors/entrepreneurs...
if I was your daughter, I would be very proud of you:)
