The state took his child away, and now is demanding he pay for them to take care of his health.
No explanation of WHY the child was “taken away” but even so the child has healthcare issues and the parent is responsible - even if the state has taken custody.
The healthcare issues of the child and the rationale for removing the child may have nothing to do with each other.
For many reasons a vacant parent is often responsible for the care and feeding of their children.
