I don't think you've got #4 correct. If you look at the beginnings of mass public education, it corresponded to the needs of the industrial revolution to have a workforce that would be content doing repetitive tasks in an authoritarian environment for many hours a day. As I watch my kids go through school (my oldest started college this year), it was clear since 6th grade that education is about finding your path to a career. The only way that works is if the education people are receiving is of value to businesses. So, while it is certainly possible for an individual to pursue an education for its own sake, the educational system is a training center for businesses.
