To believe in a one-world government, I think it’s almost a prerequisite that you don’t care about what people actually want. The only line of reasoning I’ve seen sincerely put forward for creating a central world authority to rule over all people is that some people think they know what’s best for everybody else. Not only does what actual people want not matter, but in order to achieve their utopic vision, they must protect people from themselves when they want the wrong thing.
