In addition to many wise things stated, such as school choice and accepting some kids aren't as smart as others, teachers unions (and any public worker union, esp police) need to be abolished asap.
Massachusetts is the state rated #1 in pre-K to 12 education, and they have about 100% of teachers in unions. This seems to destroy your argument that teachers unions need to be "abolished" in the name of helping students.

Yeah sorry I don't care about some click bait US News list on "best states". Also, the methodology is based on test scores which I could care less about. Being good at the SATs and ACT just mean you have rich parents that can steamroll your tutoring, which tracks with high cost of living places like Mass.
