Undoubtedly “a full dinner pail” is a great achievement as compared with an empty one, but no people ever did or can attain a worthy civilization by the satisfaction merely of material needs, however high these needs are raised. The American standard of living demands not only a high minimum wage, but a high minimum of leisure, because we must meet also needs other than material ones.
