If I were a conspiracy theorist I could envision someplace like Mars that would no way protect us from our sun burning out, but becoming a perfect bunker and escape plan for the very rich. Be some asteroid heading for earth or total chaos and war and the perpetrators of it buying tickets. If that ever happened I hope the perpetrators money in this new world would be no good and no good there. They would probably have it all set up first as well as means to continue their life style.
It’s the nature of things. Just like on earth. Bunkers for the very rich none for the rest.
