While not addressing the problem directly, school desegregation efforts usually also spread socioeconomic classes more evenly. Poorly performing schools almost always have poorer students, and bringing in more well off parents allows for things like fundraisers and increased parental involvement in things like PTAs and band/football/etc. organizations. Despite the "Karen" meme, more involved parents can also lead to problems (bad teachers, broken facilities) being addressed that would otherwise go unacknowledged.
