The first simple solution is kind of totalitarian and I don't think it's likely to be done by America. Maybe one day in Asia. Basically as part of a larger eugenics program to create more perfect humans, the State forces every male to undergo a RISUG treatment with follow-up treatments every 5-10 years. People are thus free to fornicate as they desire, and if they want to reproduce they must demonstrate fitness for such to the State and the State will arrange to reverse the RISUG. Since the State will only select breeding partners that are serious about it, there will be no abortions -- and as a bonus, no unwanted children.
The second simple solution, which I think may be more feasible in America, is to alter the abortion procedure into cryogenically preserving the embryo until such a time as a mother wishes to carry the embryo to term. This could be the original mother or not, and the birth-mother may not end up as the parenting mother. (There is a market for infertile women to pay fertile women to carry the preserved embryo to term and then the infertile woman adopts the child.) If you the original mother decide you don't want the child but are too far along in the pregnancy where cryogenically preserving the baby gives less than say for argument 50% chances at survival post-revival/thaw, then too bad, you have to carry it to term (and probably put it up for adoption) or be tried for infanticide. Research will be done into extending the period where a mother can have second-thoughts all the way up to birth (with the research also being useful for adult cryopreservation).
