In 1996 the Hoover Institution published a symposium titled "Can Government Save the Family?" A who's-who list of culture warriors—including Dan Quayle, James Dobson, John Engler, John Ashcroft, and David Blankenhorn—were asked, "What can government do, if anything, to make sure that the overwhelming majority of American children grow up with a mother and father?"
There wasn't much disagreement on the panel: End welfare payments for single mothers, stop no-fault divorce, remove tax penalties for marriage, and fix "the culture." From this list the only victory they got was ending welfare as we knew it, which increased the suffering of single mothers and their children but didn't affect the trajectory of marriage and single motherhood.
So the collapse of marriage continues apace. Since 1980, for every state in every decade the percentage of women who are married has fallen (except Utah in the 1990s):
Every state, every decade (except Utah in the 1990s): Red states (last four presidential elections Republican) to blue (last four Democrat), and in between (light blue, purple, light red), makes no difference.
But the "marriage movement" lives on. In fact, their message has changed remarkably little. In that 1996 symposium, Dan Quayle wrote:
We also desperately need help from nongovernment institutions like the media and the entertainment community. They have a tremendous influence on our culture and they should join in when it comes to strengthening families.
Sixteen years later, in the 2012 "State of Our Unions" report, the National Marriage Project included a 10-point list of familiar demands, including this point #8:
Our nation's leaders, including the president, must engage Hollywood in a conversation about popular culture ideas about marriage and family formation, including constructive critiques and positive ideas for changes in media depictions of marriage and fatherhood.
So little reflection on such a bad track record—it's enough to make you think that increasing marriage isn't the main goal of the movement.
