The top end may not be limited by money, but the bottom of education is, especially when it comes to public k-12 schools.

I doubt most people would even believe the differences until they saw them, I wouldn't of believed public school could vary that much until I personally saw it. Going from some middling school with a half dozen rich properties around, versus a truly poor rural school, showed me how true it is. The better middle school was teaching topics that the poor rural school didn't even broach until senior year. Our civics book from the late 2000s talked about the civil rights movement as an ongoing and building issue too keep an eye on, and half the school books had kid's grandparents name signed in them. Our calculus class, which was downgraded to pre-calc after a few years because so many kids failed college calc entrance exams, had a teacher bragging about how it only took her 3 tries to pass calc 102 in order to qualify for that teaching position. You certainly didn't get very many good teachers when they pay was that far below the national median wage, and it was sad to watch them struggle to afford things as simple as whiteboard markers, or copy paper in order to print student assignments on, because yes the school couldn't afford and didn't supply copy paper for teachers to print assignments on other than a literal single ream of paper to last the entire year.
