I think the billionaires are going into space because they want to be ready when the Earth gets too hard to live on.

Many think right now it's them "flaunting money" but it's really to see if they can take themselves and loved ones (mothers, sons, brothers) into space without needing a NASA type training program beforehand. Well guess what, it can be done! Next it'll either be a lottery to see which lucky individuals can go to the moon (and build structures to see if it can be done by average Joe's and also if they die form radiation it won't be a big money pit) or pros will go to Mars. From there on they'll focus on making those places habitable so that by the time we are fighting over water and fertile land, they'll be fucked off to the oasis in space.
