Well like I said, Earth is starting to get over populated. And since All of Earth is mapped and seen, I would figure many humans that are adventurousness would want to see and go to actual planets.
It's not that this particular planet bothers me, it's the fact I've lived here all my life. People often get bored of their childhood town, or the job they've had for 25 years and want to move on, I don't see why the same can't apply for planets. I'd totally love to be buried by my peers on Mars, because it'd be entirely symbolic of my entire existence: a social recluse out of superiority, not incompetence. This planet makes me depressed by the hour because of the political stupidity by both politicians and their sheep, and the fact that my homeland is being destroyed and sold out underneath me. Moving to another planet would disconnect you from all politics. I've had a theory that I've clung to for a long time, and that is "The best society is a society in progress." I have yet to see a society stay stable or true to its goals when it has completed its conquest. Once it can't expand, it always turns on itself. Back in the old days of America, if you didn't like the town rules, you skipped town and set up your own with like minded individuals. Those days are long since passed. Societies in progress tend to care less about politics and more about the people until they get a solid source of income and security.
