> We will have to infantilize people until their 30s now?

People already pick and choose who they feel sympathy for and give a pass to on the basis of their personal experiences, belief system, and social proximity. Think of how many, for instance, ridicule politicians for being too saintly and enabling or mean and without empathy then give their friends and family a pass for the exact same behavior. They'll get angry with celebrities for things that they allegedly did then shrug off a driver running a red light and nearly killing them because they "don't take things personally". Addicts are a blight on society until it's somebody's child or brother or sister in which case they just need help. Et cetera ad infinitum.

People (you and I included) are fickle. This changes nothing.
