The fact that social conservatives seem to have no interest in even exploring the use of safety net programs to prevent abortions is frustrating to me, hence the OP.
If you are talking about government efforts towards better education that leads to better family planning decisions, that is something I would be interested in hearing more about (though going through public school as a child I know that the drug and alcohol prevention education they gave us was a total waste of time and money). As far as throwing money at people after the fact just because they are not making responsible life choices is a double edged sword because many will just hear the message “I can do whatever I want because the government will always be there to support me”. That type of thinking is first of all morally wrong and second of all not even true – in the event of some crisis where government money dries up, those living on the dole will be the first ones to have quite a rude awakening.
Perhaps my mashal of somebody going around killing people is a bit “apples to oranges”. Let’s say like this – pretend we lived in a world where it was legal to kill somebody you owed money to if you couldn’t afford to pay them back (that’s probably a more apt comparison to killing a baby you can’t afford to support). Would the best course of action be to focus on changing the law so that type of thing would no longer be legal as well as focusing on teaching people how to better manage their finances, or would you prefer to focus on spending more taxpayer dollars on giving free grants to the people who can’t pay their debts so that they will be less tempted to kill their creditors?
