The average human can not even remain peaceful after missing one meal. The average engages in ritualized combat between in and out groups like football teams or company competitors. At the moment, you do not want to hand this average human a flying car with a unlimited energy supply. You do not want to hand him devices, with which he can engage in information warfare.
Now this very same human does not get better, just because they bundle together in groups that are government. They just decay different. So, what you want, is to hand this toddler from the djungle, limited technologies until the situation improves gradually. Solar instead of nuclear, bikes instead of cars, games to forget the world. And this change for a disability friendly world must feel intrinsic motivated.
