America's public schools are still promoting devices with screens - even offering digital-only preschools. The rich are banning screens from class altogether. The parents in Overland Park, Kan., were fed up. They wanted their children off screens, but they needed strength in numbers. First, because no one wants their kid to be the lone weird one without a phone. And second, because taking the phone away from a middle schooler is actually very, very tough. "We start the meetings by saying, 'This is hard, we're in a new frontier, but who is going to help us?'" said Krista Boan, who is leading a Kansas City-based program called START, which stands for Stand Together And Rethink Technology. "We can't call our moms about this one."
