If you work backwards further, you'll find you're unable to fix dysfunctional relationships through economic policy. ~40% of annual pregnancies in the US are unintended, so perhaps more accessible family planning is what is needed, so that people who don't want to be parents don't become parents.

"The world is never unhappy because of children who have not yet been born; it is grief stricken by children who have been placed on the planet without anyone to love them adequately. We can cope with fewer children, we can't cope with yet more parents insufficiently dedicated to the tasks of love." -- Unknown
Tangentially, there are ~400k children in foster care in the US at any moment in time, roughly 1/4 of which are adoptable. No one adopts them, and then they age out into adulthood. What happens next as adults, the statistics are grim (roughly 25 percent become homeless).
So, these various datasets leads me to the conclusion that we have a long way to go to help people who don't want kids to not have them (while still robustly supporting parents who very much want to parent). This, I believe, will lead to better outcomes overall. I also argue society wants healthy productive citizens who will be taxpayers and generate productivity, but doesn't give a damn about helping parents or struggling children (you would think advocates of universal school lunches were asking for someone's head on a platter, for example), so society deserves what it gets in that regard until it's ready to invest. Talk is cheap.
