From antiquity, he notes, a symptom of a civilization’s decline has been the destruction of children:
Macedonian poet Poseidippus of Pella wrote: “Even a rich man always exposes a daughter.” A 200 BCE survey of seventy-nine families in Miletus, an ancient Greek colony on the Western Turkish coast, show a combined total of 188 sons but only 28 daughters.
One Greek author, Polybius, suggested as a last resort “passing laws for the preservation of infants.” But most Greek colonies were finished already.
Rational self-interest would dictate raising enough girls to keep the population going, but clearly that didn’t prevail.
Notice that the selfish gene and group selection didn’t prevail either. Is there some way school boards can get their money back from the Darwin lobby?

It is mainly religious people who raise children, and more women in America are religious.
