You can't spend your way to a better educated population. Just like you can't spend your way to winning a war.
The money is one side of the equation, but the problem is years of neglect and failed policies from numerous administrations within ASD and the Muni. Plenty of schools are in questionable condition, meanwhile we're throwing up expensive but poorly planned replacements such as Dimond High, which is actually smaller than the school it replaced.
There's a high budget for the training teachers are supposed to be receiving, but that's going to contractors, administration trainers etc, not flowing down to classrooms.

The problem is that we're spending more but it's not getting into classrooms to help students. It's going into other areas of the district where it shouldn't be going.
