@marsxyz there's really no reason why it should cost $100k on average to get a single child through high school. aside from just administrative costs, there is so much dumb shit schools spend money on like the entire textbook industry and so much low hanging fruit that the US education system refuses to pick, like open curriculums.
educators themselves are part of the problem because they hate the idea of being evaluated and will do anything to fight things that are completely reasonable in other countries like standardized testing or literacy requirements to graduate. the school-to-prison pipeline wouldn't happen if schools were focused on their primary role (teaching students how to fucking read and add numbers) instead of their current role (expensive prison tutorial level).
reforming the educational system is impossible without public beheadings so it is actually a black hole.
