You wont, human nature is more or less fixed, cognitive skills are normal distributed, we are not blank slates. You first recognize that the problem is difficult, recognize you cannot social-engineer humans without infringing their rights and you try to come up with some basic rules with the implicit understanding that A) They are not perfect B) They are not immutable, and you start working from there. This is the total opposite to what it is happening now in the way the powerful groups are managing this new global, social landscape.
