Couple of things:
I have always believed in the Kennedy question. "Ask not what your country can do for you, Ask what you can do for your country." The words were inspiring then and seem to ring extra true these days. Some folks have a calling for military service and some the peace corp as ambassadors of good will from us to other countries. The Americore was also a good idea. As an educator I have worked with many high energy enthusiastic 20 year olds determined to make a difference. There is so much that could be done. I believe that like in so many countries, we Americans should schedule in a year of service as part of our transition to adulthood. Empathy, seeing how the others live or people who think differently then your 'tribe' would go a long way in creating a kinder country.
