Anthony Esolen at Touchstone Mag nails it:
In a sense, easy divorce is a function of the more general and heart-dampening transience. We don't tend the land with care; we treat animals as if they were no more than meat-making machines; we ship our children off to day-asylums and then to school, and when they are not at school we leave them in the care of Hollywood; we don't know our neighbors; and we, surprise, surprise, uphold no-fault divorce. That last is the stake in the community's heart. It is transience in the most intimate relation we know on earth. And we raise our children up for it: witness their "relationships," one after the other, ruin after ruin, or worse, lassitude of soul after lassitude of soul, and then they marry, and we expect them to live as if the vows they make really meant something.

UPDATE: At NPR, "Hooking up - Empowerment or loss of intimacy?"
Well said, I'd say. Of course, it fits in with our "not my fault" culture.
