How much of that goes to the teacher? It seems to be soaked up by administration.
Because of changes that mostly started with No Child Left Behind, which tried to not leave children behind by not letting them be held back when they didn't learn!
Why are kids suddenly so uneducated? Well what happened roughly one 18 year long education timespan ago? No Child Left Behind.
Further, no child left behind punished schools based on standardized test scores, not the artificially inflated grades the students were getting.
Instead, they are getting 52k per pupil to not even grade homework? That's definitely not a consequence of no child left behind.
If the home situation is fucked up it doesn't matter how much money you throw at the schools.
