"BUT...
how orwellian do you want to get here?
do you:
1) eliminate welfare child credits altogether?
2) limit it to one and done?
3) require (temporary) sterilization to continue to receive support?
4) ...other? "
The state gets it power from the people, which means any actual reversal of these trends has to come from the ground up. I daresay improvements in the level of effective parenting will pay off in a more civil and more productive society. I think this issue is arguably of more effect on the general health and welfare than universal income or gun violence issues, and deserves far more airtime in the public discourse.
Look at the post above where FF thinks the kids will be just fine. Taking that reasoning to a logical extreme if father participation in the family unit is superfluous for 25% of the kids then why not for 100% of the kids? I think this is the wrong direction, and that mocking parents for putting their family's interests ahead of their own is a bad plan, even if only from a practical perspective.
This is especially so when considering how influential parental examples tend to be in terms of how their kids will grow up. I mean, why else do parents want to avoid exposing their kids to behavior they don't condone if not in recognition of the primacy of personal example?
I think that buying the fantasy that the welfare mom is "doing it on her own" despite her reliance on the State is a profoundly dishonest play that in the long run serves to hurt the kids more than it helps them. Is that the example we want to venerate and prompt our kids to follow? I don't think so.
Same with human relationships and conflict resolution; I think personal coping skills in meeting our challenges are more effective than reliance on external codes of conduct to avoid those challenges. I want my kids to deal with their problems, not expect or wait for other people to solve those problems for them.
