The other part is the education system and lack of any predator. Since we don't have any real predators here in the US, we can safely ignore them in our education process. People like this manage to survive but fail to understand that survival is part of the process. Of course the story is the demonstration.
I am not sure, however, if we should incarcerate them. Making them into poster children might be a better thing. "I thought that my son could survive on love, it didn't work. Don't make the same mistake!".
They don't get to get any money from such a campaign though. They get to contribute their lovely countenance for free.
