But most of all, the Great Society is not a safe harbor, a resting place, a final objective, a finished work. It is a challenge constantly renewed,beckoning us toward a destiny where the meaning of our lives matches the marvelous products of our labor.
So I want to talk to you today about three places where we begin to build the Great Society -- in our cities, in our countryside, and in our classrooms.
Many of you will live to see the day, perhaps 50 years from now, when there will be 400 million Americans -- four-fifths of them in urban areas. In the remainder of this century urban population will double, city land will double, and we will have to build homes and highways and facilities equal to all those built since this country was first settled. So in the next 40 years we must re-build the entire urban United States.
