Over a long period of time I've noticed that should I or anyone else propose a complete change to some of the established but flawed systems that prevail in our conflicted world, immediately there will be an outcry.
Many people will offer a thousand reasons, some of them wildly irrational or emotive, as to why the status quo cannot and should not be changed (except perhaps at the edges). This seems to apply regardless of whether the suggested changes concern politics, economic systems, theological beliefs, social morays, nationalistic extremism, etc.
Of course to think, to re-assess one's attitudes and values, to initiate or accept change, requires energy. For most it seems too much of a disruption. It would seem as if our imitative (Pavlov's dog) upbringing teaches us to become, not vital, intellectual, questioning, creative, lateral-thinking beings throughout our lives, but dull, predictable creatures of habit (like sheep). As such, we are easily manipulated.
Worse, as long as most people are held captive by habit, the world will never change for the better (which obviously suits those who neglect or abuse their children, or who profit from war or theological superstition or political power, etc).
