We may reach a point where we have no choice ... that's the tragic theme of Interstellar.
Personally, I hope we avoid that. I would rather, when we head for the stars, follow Gene Roddenberry's vision, we do it because we want to explore, not because we've backed ourselves into a corner where we have to.
But anyway, space colonization is a long, long way off. May be a lot later than the 27th century. Got one huge problem to solve: still can't go anywhere near fast enough and the other stars that MIGHT have planets are way too far away. And the 5th dimensional beings haven't opened a wormhole for us, yet.
In the meantime, we should be working on continuing to explore the solar system, and expand the human manned presence throughout it. The Moon and Mars, at least. NASA still needs a vehicle for orbital manned missions, Space Shuttle 2.0, whatever they want to call it.
BTW, the theme of Elysium IMHO is that those who lived on the orbital space station had health devices that could treat and cure the diseases of most people on Earth, but only those on the station - a small elite - had access to them. Living in space got you the best health care, everybody else ... well they had less.
As for Passengers -- a very odd 'love' story, once you realize what he did to her.
What was also intriguing in Passengers is that Jennifer Lawrence’s character was going to return to Earth.
As for having less whether those traveling in coach class shall we say in Passengers or those on Earth in Elysium the determining factor was money. As it always is. Not even necessarily earned money but possession of money or, rather, wealth.
