I used to teach inner city kids and I had a number of Albanian immigrants and they always did very well despite being new immigrants and not speaking English at first, they told me that the teachers there have sticks, not small ones, and if you misbehave they beat you, and if you go home all beaten your parents don't complain or sue the school or wipe your tears, they beat you again for misbehaving at school. I used to think that if I actually had a stick I would almost never have to use it and there would be a whole lot less misbehavior, and then the kids would learn a lot more. In nature there are carrots and sticks, it's probably not optimal to rely on either one exclusively.

I feel bad for kids today, I bet a lot of them wish their parents would slap them, anything to not be ignored for the smart phone. Have you seen these families out to dinner with each person on their device not interacting with each other at all?
