I frequently disagree with Frum, but this is the reality today: Straight marriage is the real issue.
Just as in ancient times, traditional marriage is becoming a thing of the prosperous, educated, and tradition-minded. The solid citizens, the pillars of communities; the stable people with predictable lives.
In my humble view, marriage is, or can be, two separate things: a secular property contract, and a religious covenant. Both are quite serious matters. I happen to believe that it is a difficult and challenging, but rewarding, structure for a good life. Seems to be good for kids too, which should not be surprising.
Making relationships that work is not an easy thing, given how neurotic everybody is. It can be worth the trouble, however.
