This read failed to convince me of the former. That being said, it did convince me to pick up the author's book.
Its a bigger risk to just blindly forge ahead with kids addicted to chat, sugar and the internet.
Also the model probably breaks down into its not terribly clear how oversupervised Spartan boys were. Its still probably a historical model worth considering.
So not play exactly, but lots of peer interaction and social dynamics at work.
There are a host of other issues to contend with, my the amplification of narcissistic tendencies and lack of empathy is well documented in these cases. I can't help but wonder if the privileged children are being subjected to very similar, if diminished experience.
It should also be noted that this is not as much of a problem in poorer neighborhoods, as I see kids playing on the streets and driveways when I occasionally drive through.
