I think that most of us would find it HIGHLY offensive to take a yearbook photo of kids with household incomes over-- well, over some particular value. Why would that be objectionable? It's just an innate difference, and yet it would serve as precisely the same sort of social lightning rod.
Hmm...well, family income isn't
innate. Unlike IQ (barring head injuries, some accidents, and some diseases), it's subject to change, and a high income it doesn't affect a child's learning needs in the way a high IQ does.
I agree about the lightning rod effect, but the same could be said of the LGBT crowd and the civil rights crowd and the women's voting rights crowd. All these issues have been or are lightning rods (and to a much greater degree than just having a high IQ). IMO, the problems we face won't go away until people start coming out of the closet a bit more.
