Of course I see the dilemma. To be honest I just care more about the students who want to succeed than the ones that don't. Every student deserves a high quality education, and that just isn't possible to provide when you're distracted by other students. I care about the other kids too, for ethical as well as utilitarian reason, and I do think we need to think hard about how they can be best served. But the status quo is not working, I don't think it's fair to continue to deprive underprivileged students of the opportunities they deserve.
