It's not that easy. The status quo is that having multiple tracks creates terrible incentives among teachers: no teacher wants to teach the "bad" track, so they get stuck with the worst teachers and the worst educational outcomes over time. (This occurs not just because many remedial students have very real behavioral issues that deter the best teachers from engaging with them, but also notably because the progressive education establishment is dismissive of teaching methods that actually help those students learn effectively, and doesn't train general-ed educators in the use of such methods.)
