The above video discussion is well worth watching. It is profoundly insightful, and profoundly disturbing. I could disagree with a couple points that Simon Sinek makes, but it isn't constructive to do so.
Instead, I'd just like to make the point that the government school system has been incredibly successful at preventing children from maturing as they should, and that is actually one of the objectives of government education.
For those who disagree with that observation, I offer the following quote from John Taylor Gatto for your consideration...
Theorists from Plato to Rousseau to Frederick of Prussia knew and taught explicitly that if children could be kept childish beyond [their] term in nature, if they could be cloistered in a society of children without any real responsibility except obedience, if their inner lives could be attenuated by removing the insights of history, literature, philosophy, economics, religion, if the imminence of death and the certainty of pain and loss could be removed from daily consciousness, if the profound reflections on one’s own death could be replaced by the trivializing emotions of greed, envy, jealousy and fear, young people would grow older, but they would never grow up, and a great enduring problem of supervision would be solved, for who can argue against the truth that childish and childlike people are much easier to manage than critically trained, self‐reliant ones.
That quote comes from Taylor's short and bitter essay titled, The Purpose of Schooling— Truth versus Disinformation: Everything You Know is Wrong About Schooling.
Amazingly, it appears (from the video discussion above) that the government school system has been too successful, at least in regards to preparing young people for occupational employment. Instead of cranking out immature, easily managed employees it has produced immature, difficult-to-manage employees.
In another quote from Gatto's essay, he states that our government "educated" population is, "deliberately dumbed‐down and rendered childlike in order that government and economic life can be managed with a minimum of hassle, it’s that lowdown nitty‐gritty common purpose. Not Marxist grand warfare between classes and greedy captains of industry, it’s simply so that management will have a minimum of hassles."
Thus it is that now, even at its most clandestine and fundamental purpose, government-directed, taxpayer funded education is a failure.
