"Allocate the money for better academic facilities and programs, you know, things that ACTUALLY benefit all students and society as a whole. These vanity projects for athletic facilities benefit the chosen few."
Bonds can't be used for "programs." They can only be used for facilities, transportation and technology. It's state law.
Between the athletic teams, band, AVP programs, drill team, etc at least 1/3 (probably more) of all students directly use those facilities. On top of that, they also get used by the junior highs, by the community for things like Special Olympics and for non-district events like drumline competitions, playoff games for other schools, etc.
Team sports, music education, community involvement do benefit society as a whole. Life lessons in winning and losing, being part of a team, striving for excellence are important.
