Reading complaints a few weeks back that too many Latter-day Saints marry before completing courses of higher education, I felt concerned that a natural corollary of that is that people who don’t complete a college education shouldn’t marry at all. Perhaps the unfolding 21st Century for many will be less like the 20th Century abounding in middle-class families and more like earlier ages when bunk houses, barracks, brothels, servants’ quarters, convents, and monasteries absorbed many whose economic limitations put marriage and children out of reach, and those who want a different future will have to choose paths of their own bucking prevailing trends.
The National Marriage Project at the University of Virginia has put out “Knot Yet: The Benefits and Costs of Delayed Marriage in America” There is such discussion of the Great Crossover (mean age at first marriage passing age at first child), and a running theme is that delayed marriage plays out differently for the two-thirds of the nation that doesn’t complete a college degree.
A summary can be found at Washington Post: link. Coming at the topic from another angle, perhaps you’ll enjoy “Settle Down” by Kimbra. Or perhaps you won’t, if your tastes in song and dance don’t run that way.
