From our women and men in uniform to our educators to those who administer important government programs, each day millions of Americans give of themselves to ensure the safety, hope and livelihood of their neighbor. Without a doubt, one of the great things about the United States is the way in which the success of each of us is tied to the success of all of us. The AmeriCorps national service program, which celebrates its 20th anniversary today, is a fantastic representation of this.
