The point is that I'm not talking about a society a year or even a decade into a mission. Once the groundwork is laid, though, the possibilities emerge. The colonies didn't revolt until 169 years after Jamestown was founded. I'll finish by saying that your pessimism is unfounded, as very smart people have figured out solutions to most of the problems you have presented. Furthermore, just because you personally do not find such a situation to your liking doesn't mean that others feel the same way.
