I know quite a few teachers, and so many of them genuinely love the part of the job where they get to interact with their students and educate them and encourage them to experiment and grow. The inevitable "Why do I have to do this thing if I don't like it" is the beginning of a broad conversation about how what they're doing can be fun and engaging and deeply satisfying. Every class shy of high school has it. I rarely left the room without feeling more curious and invested in the material I was there to learn.
What fucking sucks about the modern education system is the fixation on metrics, monitoring, and milestones. Classes that used to be much more freeform and experimental have become this ridged march forward in the state-mandated lesson plan. Read the chapter, do the homework, take the quiz, tell your parents they need to panic if you got less than a "B", prepare for the exam, prepare for the exam, prepare for the exam. That's the shit that sucks.
So much of the actual curriculum is sacrificed to keep kids on a conveyor belt of assessment and evaluation. Anything that can't be strictly and objectively graded - lab exercises, independent study, school trips, artistic expression - is flensed from the lesson plan. And the only way to escape this assembly line style education system is to have parents rich enough to pay for private school or teachers daring enough to transgress against the state rubric.
