[Plato's ideal society] guarantees to all people the right to an education that diagnoses and perfects their unique talents, plus a work role that conveys a sense of self-esteem, saving them from the neuroses of megalomania and the lust for power. It forbids privilege and sexism and all other criteria irrelevant to merit. It eliminates conflict of interest from those who hold office and gives the masses a potent checklist they can use to hold their rulers to account. Best of all, it eliminates all traces of "might makes right" and serves as a pattern laid up in heaven to rank actual societies in terms of what corrupts them. Society becomes more corrupt as the struggle for power becomes more brutal.
