Children are typically taught values like tolerance and nonviolence in today's society. It's expected that parents raise their kids to be confident individuals. This is why teachers emphasize and model appropriate behavior.
People talk to children more, explain more to them, and give them more freedom than in the past. Children are meant to experiment a lot and develop into confident individuals. Parents support and guide their children with friendly authority.
