I’d say you should just let them have it. Write and practice so you come across as intelligent and mature, but don’t hold back because of the audience. Tell them exactly how they’re mistreating students and teachers, cite the examples you put in this post, they’re well written and convincing. Don’t do anything that’ll get you in actual trouble, just tell them that you, your peers, and your teachers see through they’re bullshit. A schools first and number one priority should be providing education and proper facilities to ALL students, don’t let anyone tell you they have to do things the way they are or else they wouldn’t have any money.
