“Overrun World. Davis does not think such appalling correctives need ever become necessary. Instead, he feels, futurists should accept the fact that persuasion, not family planning, is the answer to population growth. He suggests economic persuaders to encourage the postponement of marriage and the limitation of births within marriage. How? Among other methods, by charging substantial fees for marriage licenses; levying a “child tax”; taxing single persons less than married ones; eliminating tax exemptions for children; legalizing abortion and sterilization.
As extreme as Davis’s suggestions are, he sees them as the best alternative to a world overrun by people.”
