People denounce abortion as a restriction on female sexuality. But given what most of us know perfectly well about the relative frequency of the desires in question, it is far more of a restriction on male sexuality. It also tends to promote economic liberalism because if women can't rely on male financial support, they seek a surrogate husband in the state. Therefore, Republicans are paying a real price at the polls for easy divorce, and should systematically think about social policy measures designed to reduce it. Naturally, there will not be one great silver bullet to solve this problem, but every policy choice should be examined from the point of view of its consequences for the divorce rate.
Easy abortion undermines marriage by increasing the temptations to stray from it.
The glamour of the swinging lifestyle undermines the social prestige of the married condition. Since families, not swinging singles, are the only possible foundation of an enduring society, it is a mistake for any society that wishes to endure to tolerate this. Several favorable cultural consequences could be expected if easy abortion and easy divorce were curtailed. For a start, if people know that they will not be able to satisfy their sexual urges easily, they will start to demand a culture not organized around inflaming them. This would imply not just the obvious crackdown on pornography and titillating advertising, but a shift in other things like music.
