Your suggestion would work for THAT problem, but it would create another problem. It would require a police state to confiscate the child and enlarge the government bureaucracy to collect support money and oversee the adoptions.
I thought conservatives were against big government solutions like that?
The solutions to my mind have to be cultural. Children have to stop being considered a waste product of sex, or at best a nuisance outcome of sex.
And if you don’t want children, biology being what it is, the onus is on the adults to take measures (even drastic measures like sterilization) to prevent that from happening.
The responsibility and repercussions cannot logically and morally be on the child because they don’t have the capacity to prevent their own creation.
The only logical solution is to promote personal sexual responsibility of ADULTS. Both men and women.
You are making the assumption that behavior would not change in the face of severe disincentives.
The point of the article was that women with a wealthy boyfriend have an incentive to get pregnant, so as to be able to hit up the boyfriend for child support. Remove that incentive, and replace it with a penalty to the woman, and they would become much more careful to NOT get pregnant and be more inclined to want to get married FIRST.
