Gwen: How?
John: How! Why: if anybody has the quality to rise out of it, he gets on at his job, marries above him and doesn’t have children. The worst are pouring out children, the best are more or less barren.
Gwen: But, John, if the worst are increasing so much the fastest, things may get worse and worse.
John: Of course.
Gwen: Then why doesn’t somebody do something!
John: For various reasons.
Gwen: What?
John: Religion doesn’t do anything because it thinks Birth Control wicked. Big Business doesn’t do anything, because it wants cheap Labour; the Governments don’t do anything because they want soldiers for the next war.
Gwen: The next war!
John: The next war.
