While I place no trust in Plato's reasoning or evidence, I don't see the issue as "moral". Instead, I see the importance of good family formation, which the US is failing at (birth rate so low we are rapidly going extinct, literally -- the most basic failing of a society), and needing solutions good in all or nearly all respects.

Failing at family formation is no darned good and worse -- it canNOT last. On this point f'get about Plato, Fromm, or me and, instead, listen to Darwin -- yup, he's on the case.
