They assume (correctly) that most of these children will be kept by the birth mother at minimum, or forced to be kept if a birth father intervenes.

The parents will pay child support and continue to live in whatever shitty situation they were in when they had the baby, the baby will always be a source of contempt even if loved, and then it will grow up to be a good little soldier or worker.

That's why despite all their blustering, adoption is NOT put front and center as an option. That was only brought up when women could still consider abortion, as a deterrent. Now the option will only be brought up if the mother aggressively pursues it.
