Or teach things that would be useful like finance and trade skills, not be allowed to include identity or sexuality as part of the curriculum and instead stick strictly to STEM fields, remove standardized testing and its restrictions on learning, more class time than homework time (not remove homework at all), mandate that all teachers be armed and have regular and up-to-date firearm training, stop teaching stuff they won't use and stop at an adequate level of math and writing (fun fact: many pre-requisite classes in college are the same things you'll learn in high-school, so you're paying tens of thousands for the same stuff!), ACTUALLY deal with bullies, allow later start times for high school students, stop affirmative action school policy, and disallow teacher's unions and those who author the curriculum to have any political involvement or influence while allowing parents to regularly get involved instead.
