There is a point at which material things offer less than do some nonmaterial things. We ought to be able to live on a reasonable level and at the same time have others live on a reasonable level. Then we would not be afraid to work in our cities, we would not be at war with ourselves, which is characteristic of people in this country. If we were at peace with ourselves, we would be able to see other less material, but still quite rewarding, horizons. In The Greening of America, I did not mean that we would all become richer in material things, I meant that we would all become richer in the totality. I still think it is possible for that vision to become a reality.
