I agree, but I think "kids who are actively harming the educational system" and "gifted kids" is a false dichotomy: the spectrum of "kids whose educational experience is damaged by bad apples" is wider than the gifted kids discussed in this article, and by only helping out that small subset I think we leave a whole bunch of kids left hanging (and arguably the ones who need a strong education the most.)

(Our high school's approach to that was just offering "study hall" as an elective, with the implication that you could just skip study hall and nobody cared.)
