The United States is the most illiterate country in the world--that is,
of the so-called civilized countries. Of the 5,000,000 illiterates
in the United States, 58 per cent. are white and 28 per cent. native
whites. Illiteracy not only is the index of inequality of opportunity.
It speaks as well a lack of consideration for the children. It means
either that children have been forced out of school to go to work, or
that they are mentally and physically defective.(1)

One is tempted to ask why a society, which has failed so lamentably to
protect the already existing child life upon which its very perpetuation
depends, takes upon itself the reckless encouragement of indiscriminate
procreation. The United States Government has recently inaugurated a
policy of restricting immigration from foreign countries. Until it is
able to protect childhood from criminal exploitation, until it has made
possible a reasonable hope of life, liberty and growth for American
children, it should likewise recognize the wisdom of voluntary
restriction in the production of children.

Reports on child labor published by the National Child Labor Committee
only incidentally reveal the correlation of this evil with that of large
families. Yet this is evident throughout. The investigators are more
bent upon regarding child labor as a cause of illiteracy.

But it is no less a consequence of irresponsibility in breeding. A
sinister aspect of this is revealed by Theresa Wolfson's study of
child-labor in the beet-fields of Michigan.(2) As one weeder put it:
"Poor man make no money, make plenty children--plenty children good for
sugar-beet business." Further illuminating details are given by Miss
