What do education and mental health issues have to do with this?
And far as I can deduce, civilization boils down to sanity and thoughtfulness. The rest is window dressing and 'product'. (I am /not/ dismissing the fruits here, but rather focusing on 'roots'.) What is necessary is sanity. What is necessary is the ability to think effectively. Individually and collectively. Everything else is secondary, and if the former are lacking, abundance in other dimensions only gets you so far and then it peters out.
