In a full democracy, there is going to be a large diversity of opinions. If we allow everybody to do as they want to do, based on their own opinions, society will never focus on a point at which to advance greatly.
Evidence in the form of: Twitch TV's "Twitch Plays Pokemon", a ROMhack of Red Version, in which around 50,000 people are fighting for control of the game with their own simultaneous input. If there is a large and popular opinion that overpowers all of the others, the group will inevitably move towards that goal continuously, forming a current. The same way a current pushes water along a set path down a river, or in an ocean, it will push society towards change. Just a bit ago, there was such a powerful desire to acquire Eevee, it overpowered the desire to not to acquire it (and get Lapras instead), and thus the group ended up getting Eevee. The group, the society, advanced greatly in one direction.
There need to be articulated directions for society to go in, based upon mutual agreement among the most educated and empathetic collection of people.
Rationalize, collectively, which form of education is the most beneficial to a society, in general. Plant the seeds of that form of education across the globe, and let the seeds grow inside of the nations of the world. As time goes on, plant the seeds of other rationalized directions for the society to go in, and form layers upon layers of reform, by planting the seeds for their movements in a deliberate order.
