One of the things that I've given large amounts of thought to is the idea of a unified planetary government--the abolition of nations as we know them to incorporate all humans into a unified federation. All of humanity finally united under the banner of a single, world-spanning nation. The way I see it, it is a simple, natural, inevitable last step in human social evolution, following on the heels of globalization and the ability of information technology to link people together from anywhere in the world. The history of humanity is dominated by a steady increase in the size of social groups. From family, to clan, to region, to principality, to nation. It is only natural and right that we take the next step into total unity. And when all of humanity is united under one government, and competition gives way to cooperation, the amount of progress to be seen will be astonishing. When this ultimate stage of human social evolution comes, it will usher in the most prosperous era humanity has ever seen. For this is the final necessary step for humanity to begin to spread from its earthly cradle. When all of humanity is united, with one goal, we can take in unison the step outwards from Earth and into the vast unknown reaches of space. This goal, this ultimate objective, will be achieved through a variety of means. When the spirit of unity replaces nationalism as it is destined to do, there will still inevitably be those who oppose this objective. The path to unity will be dangerous and tough, but the greatest virtue of humanity is that when a group of like-minded and determined humans sets their mind to do something, there is nothing they cannot accomplish. Unity will come, and I believe that it will come soon--within our lifetimes. Ideas are encouraged, comments are welcome, and questions are smiled upon.
