Note that access to reproductive care continues to be impeded on in places like Utah and Texas - see the recent filibuster in Texas by Wendy Davis, for instance, or Utah's "abstinence-only" school curriculum. It is not usually middle class families hurt by policies like these (e.g. Utah's laws assume the parents will deal with sex ed, and by and large, middle class families do just that).
Instead, abortion/birth control restrictions and/or poor sex ed hurt lower educated, lower income families. Single moms (whose husbands are in prison) have no time to ensure each of their kids gets proper attention, have no control over the next pregnancy because lack of education/PTO to drive to the next state for abortion, new child is born, cycle continues and unintended pregnancy rate for people below poverty line increases.
When you remove and important and often sole provider of family planning, the planning part goes astray.
My biggest question is who profits from eliminating places like that? I don't buy that it's just about abortion and religion (and therefore politics, in the US.)
