I'm no historian, but my best guess it that it's just correlation and that the main underlying cause of "civility" is wealth. When your citizens are struggling to survive, they (at least in their own minds) don't have time to think about women's rights, racial prejudice, etc. The progressive countries of the world just happen to be a few decades ahead on the technology timeline. There are obviously other factors, but I think that's the big one.
