The world has become an amalgamation of centralized blocks of power on the one hand, and a move away from these blocks on the other. The latter happens for good reason. Not that any such reason should be required. The plain and basic human right to, and desire for, freedom and self-governance should be enough. It isn’t, though, as we shall find out soon enough.
The centralized blocks have been able to gather far too much power, politically, socially and militarily, all concentrated in the hands of far too few people. And because we are who we are as a species, once you arrive at that sort of power concentration, it is inevitable that the people who go look for it, and obtain it, are the last ones who should have it. That is, from the point of view of all the rest of us.
It takes a certain mindset to want so much power over others, and if you don’t end up with outright psychopaths holding the reins, you’ll get something very close to it. Nevertheless, on the other hand, the process of increasingly concentrated powers is a natural one.
