I agree with you, but on some points I don't. First, not every single mother is on welfare, and likewise many dad's pay support. Regarding this particular article, and related issues, yes there are many mothers and fathers who have defaulted. There are also many young women who see single motherhood as an "out"(consciously and subconsciously). If they have a child as a single mother they can go on welfare and get their own apartment, groceries, medical coverage, etc. Dad is just a vehicle to get where they want to be, and it suits dad just fine. Meanwhile, in many instances, these young women have escaped their families dysfunctions. Unknowingly, and vice-versa in some cases however, the responsibility and joy can turn into a burden and the cycle of dysfunction is carried on.
My point is if the government didn't create an "escape" route for these young women (teenagers, too often)that included more innocent victims and pawns (children born to them), then we'd have far fewer irresponsible single mothers out there. Should we have a temporary saftey net? Sure, but short term only, not to be used accessively.
If one realizes how difficult it is to raise a child alone, economically, emotionally, physically, spiritually, intellectually, in reality every single area of one's being, then the numbers would be reduced. Would the children suffer? They already are, and don't kid yourself that they aren't.
