The logic is hard to challenge. Even if it seems convenient to abort in the short run, that factor can pale, given the prospect of a lifetime of existing with what might have been. True enough, a child, or another child, can affect family budgets negatively. Two heads might be better than one, but it costs more to feed two mouths, not to mention providing clothing, other necessities and eventual college tuition. Careers might be delayed also, if a newcomer is accepted instead of aborted.
Somebody has to care for the child, after all.
Even if the State condones abortion, or encourages it, potential psychological fallout cannot be avoided. What goes on in legislatures and courtrooms is not the same as what a given woman thinks and feels. Politicians and judges can make their laws and rulings and forget about them. Whatever emotion might be felt recedes quickly in the ongoing rush. Although any or all of the above considerations should give pause to women considering abortion, they are still not the whole story.
