To be perfectly blunt, it is extremely rare for white children - especially ones with blueblood pedigrees - to receive need-based scholarships.
The Park School serves Baltimore, a city that is 65% black and more than 70% minority - it is not that the school has a shortage of traditional need-based applicants.
I don’t personally know that these particular children DID get scholarships. I had just been pointing out it was a possibility.
