“Take away the monetary rewards from the state and you would see a lot less absent fathers.”
There are also many single mothers who do not pursue support, either...for one reason or another.
The states have everything to do with it. Every dollar of support is matched by the Feds so it behooves the states to destitute the fathers. I think both parties should be financially responsible for the children not just the fathers.
If it was “for the kids” as they say then whoever makes the most money should get the children. Custody should be a simple case of both parties presenting proof of income and whoever makes the most gets the kids.
