>Its sad, but the question we need to ask is, does the government have an obligation to provide the best opportunity for the child?

I don't think so. The government has the obligation to preserve the general welfare and public order - providing opportunities for any particular child is entirely the obligation of their parents and community.

Unless there's an actual law being broken - and as far as I know, being mentally incapacitated is no crime, and according to the article, there were no signs of abuse - then the government shouldn't get involved.
