I may be old fashioned but I don't believe that the basic "kid" has changed that much. But I do believe that there's so much going on that it's overwhelming. Like you said it's the rotten stuff that makes the headlines, and we know what's going on everywhere. The world has changed. While it makes it possible for me to have this conversation with you, the pace of the world is changing the world. I don't mean that there's been a huge shift in the balance of good and evil but that we're more aware of the world. The more I know the more I can understand. On the otherhand, that I can know more tragedy from around the world doesn't mean there's more tragedy around the world, just that I know about more. I hear that violent crime has gone down but when I hear about someone murdered almost every night that sticks with me longer than the numbers. And if you show their face...
If I think parents have changed, I think discipline has changed. While I don't think "beating them within an inch of their life" is an option, I think children should be expected to act in a reasonable manner. I'm a big fan of Teaching with Love and Logic. Or Parenting with Love and Logic by Jim Faye and Foster Cline. I believe even today kids have the capacity to make good decisions if we give them the tools. Parents who teach their kids not to respect their teachers, gasp, have children that don't respect their teachers. Then there's not a whole lot of learning going on.
I think being there for kids is huge. I don't believe everyone should quit their jobs. Both my parents worked but I knew they were there for me. I believe there are some kids wired to succeed no matter what. But the rest need some wind in their sails. Either a parent, a teacher, a neighbor,... someone who lets them know there's something good in them and helps them polish it to shine. If when kids look around and all they see is negative, it's hard for some to understand there's more out there. A good role model/example can go a long way. I'm still a big sucker for an encouraging word. Don't wait for the headlines to change. Start spreading the good stuff yourself.
