That's not coincidental, the modern compulsory school system is designed to create 3 things: nations, worker drones, and soldiers, and pretty much in that order of priority.

excerpt:
I teach the lesson of dependency. Good people wait for a teacher to tell them what to do. This is the most important lesson of all, that we must wait for other people, better trained than ourselves, to make the meanings of our lives. It is no exaggeration to say that our entire economy depends upon this lesson being learned. Think of what would fall apart if kids weren't trained in the dependency lesson: The social-service businesses could hardly survive, including the fast-growing counseling industry; commercial entertainment of all sorts, along with television, would wither if people remembered how to make their own fun; the food services, restaurants and prepared-food warehouses would shrink if people returned to making their own meals rather than depending on strangers to cook for them. Much of modern law, medicine, and engineering would go, too - the clothing business as well - unless a guaranteed supply of helpless people poured out of our schools each year. We have built a way of life that depends on people doing what they are told because they don't know any other way. For God's sake, let's not rock that boat!
