I mean I agree that that's not the perceived thrust of the article. However, parental neglect is largely a product of the environment. Parents rarely just naturally don't care for their children. There's usually other factors; stress, debt, addiction, mental health issues etc... . These are things that a state can provide support with. It's very challenging to access good quality talking therapy, for example. And a well-funded welfare system could do more to identify children in neglected situations, and to work with the families to bring them out of it.
