You can see how a globalist regime will have the same problems, but at a global level, as natinalism, when you look at the various wars carried out internally in the US. The war on drugs, the war on terrorism, with all the attendant racism, classism, fascism, surveillance, and incredible incarceration rates. Soviet countries of course carried out similiar wars against their own people, earlier in history often around betrayals of the regime. There is absolutely no reason to assume any of this would stop with a global government and there are many reasons to believe it will actually increase. 1) there are people whose temperment is suited to this kind of top down control. They will no longer have to compete with other countries for being the good guy. 2) Control of media and information will be easier. Right now the complexity of viewpoints is somewhat protected by there being so many countries, so many propagandas which do want to get at negative truths about other countries, media corporations that are not unified with all countries by semi melded with one or two. After a final merger of all governments, the oligarchy can eliminate, streamline control. 3) the larger a country, the greater the distance from the supposedly represented or at least serviced by the government. Even a Senator or a member of Parliment or some Communist bureaucrat is fewer degrees of separation from all different kinds of people, than the government members, the law enforcement members, the military members of a one world government. A litle nuancing, send region 1 troops to put down resistance in region 6 if you are concerned about vestiges of national or ethnic identity causing some reluctance, can make things run smoothly. But basically accountability is even less likely. They are really far away, dealing with people even more as statistics who they will never meet the cousin of or share a favorite professor with or run into somewhere or have ones cousin run into. It is pushing bottons and dealing with numbers. To an even greater degree.
Control of information, the systematic inhibition of even the last vestiges of empathy due to the centralization, and the easy to find excuses for survellance, control, monitoring and law enforcement/military use internally set up for the worst possible scenarios.
One might argue it will just be a coin toss. A good one world government will be just as likely as a bad one. That is one fucking dangerous coin toss and I don’t think it is worth the risk. But further I think it is much more likely to be a bad flip. A single world government will have to have an incredibly deep hierarchy which leads to the even greater loss of empathy and distance issues I raised. It also acts as an enzyme for control by wealth. Oligarchies begin to accumulate wealth in smaller and smaller groups. Even tyrants of smaller countries had a kind of self-image investment in maintaining the lower classes with some degree of survival.
Toss in the technological advantages oligarchies have, coupled with control of the minds of children and you are baking a really bad loaf here.
I have generally had much better experiences with mom and pop stores than corporations. Eye contact, they know me, human to human.
When I try convincing a rep in India that my American sold to me product made by Chinese workers out of parts made wherever is not working and I should have compensation, just the very inertia of working my way through the corporation is oppressive, in the best of circumstances when the corporation actually decides, in the end, I do deserve help. And when they do not I am actually talking mainly to recorded messages who give me false dichotomy options to press.
And wait until a one world government gets an AI and robots or transhuman organism/cyborgs as tools.
Sure, it is a nightmare if a number of nations get these and use these, but at least they then have other enemies than us to use them against.
Attention, nutter at bay.
