How much of that is being spent on things entirely irrelevant to education, such as administration, "school sports" aka baseball/football stadiums and other amenities?
As much as I hated my HS principal, you still need administration. Sports, are underutilized and also needed by healthy humans. Sure, some schools disproportionately spend on sports, but they are in the minority, and tend to self fund. Why not kill art, music programs too? Just email assignments and hope for the best...
