One of the big issues is that school districts get funding based on things like property taxes, or geographic location. The result is that affluent districts or schools are will funded and have good services, and others do not. There may also be some willful underfunding in some places as well by folks that balk at any taxes or bonds that don't help them immediately.
However, even an underfunded district should have been able to see this plan would have issue and raised a red flag with the community in advance.
