Well, I believe it is important for moms with uninvolved dads to be funded in such a way as to be able to spend as much time as possible with their kids, especially in the first two years of life when babies should be breastfed. Kind of hard to breastfeed when you are working FT and trying to scramble to do 100% of the life chores.
Also, kind of hard to most moms to rack up baby daddies. Once you are preggers and have a baby in tow, it sort-of effectively takes you off the market so to speak. I know women have repeated unplanned pregnancies, but it is often to the same baby daddy! So neither the women nor her man are learning from their past choices. (i refuse to call any child a 'mistake').
Anyway, as much as you might deny it, I see it firsthand in my clinic. And dads just usually aren't willing to clean up the hot mess they make in women's lives, or take responsibility for it.
Why should a woman's parents have to support her babies?
Also, I corrected my post. I posted 100% of dads do not get involved but that is not the case, upon reflection. However, I would say most are uninvolved or at least reticent about becoming involved to the full degree necessary to provide fully for the needs of the child. And it necessarily falls to the woman then, and consequently, the state.
Look, the state would not be getting involved if they did not have to. The weak point is the absentee fathers, like it or not.
