If you actually think about what it is to instill knowledge and intellect, schooling is so far off it isn't even funny.
Schooling is being managed, many times, by the same people that manage businesses. It is less about helping students to learn and more about making the "business" run as quickly and efficiently as possible while meeting your goals and objectives.
In my opinion, many times these managers LOVE to TALK about how to make connections with others and what the "right" ways are while never actually making connections or doing what is right.
Any teacher that starts out genuinely interested in helping others is quickly bombarded with "goals and objectives" created by people that don't have a clue about teaching. They are judged with idiotic metrics that really don't measure anything of true value. Some teachers are so passionate about teaching that they ignore the metrics and goals and objectives, instead focusing on making connections with the students and doing what is right (See my last paragraph to realize the sheer stupidity here.) Then that teacher is "let go" because they aren't of value to the business, er school.
Eventually any teacher is so perturbed that there is no chance in hell they could adequately teach the way they need to.
You can have the absolute best cirriculum in the world, but if the teacher doesn't give an F, it doesn't matter much. My best teachers threw out the cirriculum and did their own thing. ALL of my classmates paid attention and loved the class, and we actually learned...
There are bad examples of teachers throwing out the cirriculum too, but that's life.
