I read this article and it made me sad. The middle school in question is Marina middle school. I don’t know it well but I know San Francisco has always had a disproportionate number of its students in private schools (in relation to neighboring cities and the state). I wonder if the numbers have changed recently. Some San Francisco friends that had the money put their kids into private school (and it was not easy, interviews of kids, parents, essays etc.) and some others of more modest means would move once the kids reached school age. It’s been a while since we lived in the city though so I might be behind on my observations.
