Then what is the proposed solution? Pointing out the problem is the easy part. But if you want more people to be married, and if they're currently choosing not to get married, then you need to either force them to get married against their will (institutionalized shotgun marriages) or incentivize them to get married by offering benefits to married couples. The former produces miserable, abusive marriages and traumatized children. And as for the latter, as a country we're already utterly incapable of allocating funding for the aid of childrearing--where's the guaranteed maternity/paternity leave? where's the socialized childcare?--so pardon me if I don't quite see that solution as politically feasible.
