I agree that property tax funding has been problematic, but even without being the main source of funding our schools are very underfunded and inequitable.
Furthermore, I went to an out of district public elementary in an affluent area where the PTA easily took in a couple hundred thousand per year from parent donations to fund extracurriculars and other educational programs that were being cut elsewhere (art, music, science lab, library) - I say that to say, our system is designed to have/allow “less than” schools…so again, we shouldn’t try new options to get underserved kids access to quality free schools?
