I think you have to look at the marriage issue in light of economic prospects as well; if college classes have been 60%+ for years now, there is a ripple effect where more and more men can’t sustain a family. Some that try watch their wives simply leave for a more financially secure man, so they lose their wife and any children (for all intents and purposes).
Word-of-mouth has spread word of the risks much more effectively than the media can suppress it...
But that would be occurring far less if divorce laws found fault in adulterous and rent-seeking behavior.
Of course the divorce laws (and now laws redefining marriage as well) would not be as disastrous for our nation as they are if Christian culture remained the foundation of all laws.
