Coming from a public high school in the Bay Area I can totally understand the issue of AP/Honors or advanced math classes having the effect of segregation based on socioeconomic background. It's a tricky subject but I was able to take algebra in 7th grade which set me up to take calculus in junior year all through what the public schools provided which I was extremely greatful for. Personally I think it would be a shame if these classes get removed even though I understand the sentiment.
