I would think that most people agree that diversity is good for EVERYONE.
Different culture brings different strength to the table/campus/society.
Chinese, for example, are traditionally good with grades, but don't
necessarily excel at social skills, independent/critical thinking etc .
Personally I would want my kids to attend a school with people from all
races, cultures, socioeconomic status. I want him/her to have different life
perspectives and point of views.
Private schools are actually competing (and winning) with public schools for
good minority (black and latino )students, as people sincerely think that
ALL will benefit from diversity.
