There are private schools all across the country, places with better resources, better teachers, better budgets. By definition, these schools are not for the public. They are private. They are exclusive. They are for those who can afford better. Rarely does that include black students.
In the 1960's, it almost never did.
And then there are the ultra-elite private schools, the super schools; places where the resources, the curriculum and the tuition are comparable to the best liberal arts colleges. These are schools where lineage is a factor in the admission process. These are not schools for those who can afford better, they are schools for those who can afford only the very best.
These are places of privilege.
