This is a really concerning (and common) response to the hypothetical situation where a parent is putting in non-stop effort to try to do what’s best for her kids.

But as in divorces the state cares about child well being not how much efforts the parents put in.

I agree that the child’s well being should be primary concern, but I mean to say that if a parent is doing everything and anything we hope a parent would do, and they still can’t reach what the law says is a “minimum level of well being”, then that should really be looked at not as a failing of the parent, but as a failing of society.
