Ohhhhhhhhh, Barbara, you cut me to the quick! Yes, the computer fix at the end was too facile, but the movie remains the strongest protest against race prejudice I've seen. The inhabitants of Elysium are all white, while most of the earth's remaining population are latino. White Max is still on earth because he'd stolen cars and was an ex-con, just part of the human detritus left behind. There's a lot of anger in this movie, and it's directed at immigration laws (like the two ships carrying "illegals" that are shot down rather than being allowed to land on Elysium). Violence begets violence, and the movie is saying that's where we're heading.
