Truth is in the middle.
I grew up in the Ukraine in a culture oh so different from the US. I was "a good teen", but even so, I remember bursting into tears without a cause, I remember saying foolish things that were out of my head by my early 20s.
If you go to Cambodia, they will tell you that Khmer Rouge used teenage boys to torture prisoners, because they were more willing than adults to inflict pain.
Now, I can't disagree that "child-adult continuum" is important. But, he says that everyone is brainwashed, and kids don't want to spend the time with adults, and don't see them as someone to look up to, and the adults don't know how to reach out to. Yet, who brainwashed Mark Twain to say:
“When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much the old man had learned in seven years.”
The old African proverb about "if you don't invite the youth to the dance, they'll burn down the village" again points to something that this speaker is not recognizing.
And he should come and visit a country where public school is not necessary past the age of 14... It's NOT something you will want over here, and as PP mentioned, it's not something women will want to relive.
What do I agree with?
I think not shying away from giving teens more responsibilities is a great idea. I think it IS worth to look at how high schools are set up, it would be nice to change things around on a more technical level, and I speak as a public school teacher who would LOVE to change the way schools look, feel and educate. I think it's a great idea to create opportunities for teens to have more interaction with adults. I think it IS very much worth examining how to change education system, but there is good and bad in every place, and it is a bit simplistic to blame everything on the drug companies, imho.
