Maybe. But no one is forcing people to get divorces or not to marry in the first place. They’re making that decision on their own, which leads me to believe that they’ve concluded that marriage isn’t useful to them anymore.
And it isn’t “useful” to them anymore because... wow, even that statement sounds incredibly narcissistic, it’s all about “what’s in it for me”...
anyway, because our society has denigrated the values that support marriage - Sex, children, mutual support.
