Why on earth wouldn't a woman get a divorce if she was bored with a perfectly faithful and non-abusive husband? She doesn't have to prove infidelity or abuse, and the husband is powerless to prevent her from achieving a divorce if she wants. She's almost guaranteed to get the house, the kids, and if the husband is making a decent salary, thousands of tax-free dollars a month in child support. A discontented woman has zero to lose, except a husband she's gotten bored with.
If "family law" (an oymoron in the U.S.) changed the laws so that, for example, there was a cap on child support of say, $600 a month no matter the husband's income, or that "shared custody" wasn't the scam it is today but was actually "shared" in that the kids spent equal amounts of time with dad as with mom, or that mom (who gets custody about 90% of the time) was required to prove that she actually spent the child support on the kids ... THEN I think we'd see a significant reduction in single moms and fatherless homes. But right now, women bored in their marriages have nothing to lose by getting divorced.
Except divorce is not the primary cause of single motherhood, it is the non marital birthrates exceeding 70% among blacks and hispanics.
Divorce is not the problem, it’s never being married in the first place.
