If that's the case, then Max just made the world much, much worse.
well, that's what's interesting, the film doesn't bother trying to answer whether that was a sustainable solution or not (most likely not, which is part of why Elysium was set up the way it was), we just know Max did what he did for Matilda and there are widespread, immediately positive impacts that happen but may not necessarily lead to a brighter future. the ending is bittersweet at best, but the film posits that there are some things that are still worth doing because who knows what our children and our children's children will be able to accomplish in dealing with the problems that humanity will inevitably and always face, just so long as we enable them.
