> From the start we assume that the gifted deserve more from public school, thus we call them "neglected" when they seem to be simply treated the same.

If you have a group of animals where most of them are dogs but a few are cats, then use statistics to justify treating them all like dogs, that is not fair to the cats, is it?

The issue is deeper than that: it's that we take some singular conception of what a dog is, and ruthlessly beat any deviation from that idealized dog out of all the individual dogs. Which ends up being every dog.
