No more than public school is a "means to control humans".
It's social indoctrination. Consider the Amish or Mennonites. They are clannish, stick with their own and are united by their faith. You've seen me write about the adverse consequences of eliminating the draft where the military indoctrinated people to unify to protect the Constitution. After the draft ended, we had "the Me Decade" and, 40 years later 1/6 which was a demonstration of "me, me, me". They didn't give a shit about the United States, their fellow Americans or anything except themselves. Without a common cause and common beliefs, people drift in different direcdtions.
This is why I always laugh at the anarchists who think humans can exist without government in tribal societies. Sure they can, until some city-state army comes by, takes their food, livestock, women and burns their huts down. LOL
