[ Because the “educated” people in media actually want there to be a one world government. ]
The media people, most of them, think the one world government would be like something out of star trek, but that won’t work because actual freedom in societies is actually a rarity. Most of the world lives under tyranny, so if you mash all the countries together you will certainly get a Tyrannical regime. If all countries were like the USA was 50 years ago and we mushed them into a world government then maybe there would be a “world government utopia”, but even then the odds and human nature would be stacked against it.
