The death of marriage is not inevitable. In a given country, public policy decisions and cultural values could slow, and perhaps halt, the process of marital decline. Nor are we faced with an all-or-nothing choice between the marital system of, say, the 1950s and marriage's disappearance. Kiernan's model posits stopping points. So repealing no-fault divorce, or even eliminating premarital cohabitation, are not what's at issue. With no-fault divorce, Americans traded away some of the marital stability that protects children to gain more freedom for adults. Yet we can accept that trade-off, while still drawing a line against descent into a Nordic-style system. And cohabitation as a premarital testing phase is not the same as unmarried parenting. Potentially, a line between the two can hold.
