I think the guy who wrote that article has serious issues. I would not want to be his friend, student, coworker, OR child.
Telling ANYONE, child or adult, that nobody cares what they feel is not only cruel but invalidating. There is already enough invalidation going on in people's lives - many kids and adults are constantly told that their thoughts, experiences, and feelings are unimportant. Yes, it is important to learn whatever the curriculum is, but doing so at the expense of invalidating a student is destructive.
That, and he has the nerve to say young people today are spoiled, when his parents paid for his entire education. I sure wasn't that fortunate.
The formative years ARE important. Devoting time and attention to ensure children grow and develop in a healthy way is crucial to society's happiness. IMO that is not the same thing as spoiling them (and spoiling them does need to be avoided).
