If someone cannot afford to feed his or her child and the child starves--literally or metaphorically--who's bearing the responsibility?
Edit: To be clear, I agree that you shouldn't have a child you can't afford, but mistakes happen, situations change, etc. It's a lot more complicated than the commonly portrayed notion of welfare mothers defrauding the government.
@brown9-2 In theory it does, but if businesses don't hire said unwed mothers because government policies make it too expensive, it doesn't benefit anyone.
