I respectfully disagree.  We know abortion rates go down when people have jobs or at least a social safety net that enables effective access to adequate housing, potable water and safe food.  Even St. Teresa of Kolkata stated when she was at Harvard that it was the fear of not being able to provide for another life that lead to so many abortions.

And if folks really wanted to reduce abortion ... how about enabling contraception.  

AND then we could challenge our current dominant development mode for promoting such gross materialism and consumerism ... without which it grinds to a halt.
 And on and on ...

A seamless garment continuous ethic of life/solidarity makes these connections.
