The GNP by itself is no mark of our national achievement. For it includes smokestacks that pollute, drugs that destroy, and ambulances which clear our highways of human wreckage. It includes a mugger's knife, a rioter's bomb, and Oswald's rifle, but if the GNP tells us all this, there is much that it does not tell us. It says nothing about the health of our families, the quality of their education, or the joy of their play.
