"You really think 6 billion people can live as a big friendly family without divisions? Its fantasy. Its called human nature.
6 million people can live without engaging in wars, or living in privation, which in turn will yeild unity and democracy. There will still be alienation, but significantly less alienation. And once law is simplified, and leadership restored, there will still be crime, but significantly less crime. Prisons will be rehabilitation centers, not mostly, destructive experiences.
You seriously believe that no organizations are going to spring up between people which will oppose each other? Or personal conflicts will get out of hand? Or racism will go out the window? That people will not be taught to hate one another, and hold prejudice? You do not believe there will still be deranged individuals, individuals who live lives of hardship and turn to crime?
You must be joking.
