Actually, what education is for is to prepare my child to take entrance exams to college. That is the sole purpose of schooling. There are other nice benefits, but they are not the reason I send my kids to school. I am my child's parent. It's up to me to make sure they aren't socially awkward, that they know the importance of showering daily, they know the dangers of per-marital sex, if needed, it is my job to find a babysitter (a teacher is not a babysitter), it is my job to make sure they study at night and actually learn the material that the teacher is presenting.
The whole point of school is to learn a skill that will help the child be a normal, functioning adult. In my opinion, the easiest way for my kid to enjoy their adulthood, is to become a professional. It is up to me to give my child the tools, motivation, and skills to become that. It is up to my child to use those tools. It is up to the teacher to get my child ready to take entrance exams.
