What is it like being an alumni of a school that’s underfunded or neglected? Even if the school is “good” (as in well funded or private), does the learning environment reflect that? Also, the dark side of American schools (shootings) dampens peace of mind for parents since at any given moment some gun wielding individual can storm in murdering those inside (students, teachers, custodians, etc.)
There’s no one “American” educational system.
Under the Federal system, each State regulates itself, and each town can do what it wants. Two towns in the same state can have wildly different standards and outcomes, depending on the local Board of Education.
