Depressing quote from San Francisco Chronicle article entitled, Many reluctantly choose private schools:

“The best private school is, in my opinion, better than the best public school anywhere,” said Pamela Singer, whose daughter, May, attends Convent of the Sacred Heart Elementary. “When you take a group of people who have money and they just pour money into this school, and they’re already like-minded because they’ve chosen to join this club together, it’s just going to be elevated.”

Yep, there’s really nothing like homogeneity and conformity.
