I imagine that family-centrism makes it much worse for the minority who have abusive narcissists for parents.

This is a problem in every society, and must be addressed in a different way. If the role of government is to provide its children with a fundamental understanding of themselves and how to manage their individual motivations, perhaps the resulting adults will be better equipped to rise above their parents' shortcomings? Strong family and team dynamics will pull how healthier people live into stronger contrast in such a situation.
