Kim Stanley Robison's Red Mars explores exactly this problem of colonising a new world whilst the old world is brokenly unequal and has ecological disasters tearing it apart. Really good book. I won't spoil it too much, but think it offers a powerful challenge to the techno-utopianism of Mars Colony obsessives. The Martians cannot escape their terrestrial ideologies, because those ideologies are still rooted in the old world that they rely on for survival, and because they carried over those ideologies in their own minds.
