Are you validating my point? Less than 1/4th of all children in one of the wealthiest metropolitan areas in the country.
Also, I don't believe that you are more invested in the 90% over the 10% unless the 10% is a group you disfavor -- such as parents who refuse to condemn their children to bad public schools if they can help it.
It's oddly transparent to limit your stats to white people.
