Three things.....
1. You forgot to post 'spoilers'
2. Theres no intellectual laziness about this film. The only problem with the film is that it wasn't longer, giving us more time to experiences larger parts of the story, which could've branched out in many ways and realized more characters than just Damon, himself.
3. The story holds a fundamental truths about the future if things continue the way they are going:
A) In the next 30 years the US will be taken over by hispanics. They will be the majority in the nation.
B) The disparity between the rich and poor will continue to grow whilst many people will have to work multiple jobs just to make ends meet. This world is over one hundred years later than even that.
C) Medical coverage has to become increasingly socialized on a larger scale to meet the demand of the sick and poor.
D) The rich flee for space (Smart plan). Lets look at what the poor do to the rich in south and central America when they are desperate.
E) Corporations and making deals with governments to ensure stability and power without the the consent of representatives of the people or even the people themselves.
F) Computers become a part of our lives and are now connected to our minds, even in a poor and impovrished world. You act like hackers today don't have issues with governments.
G) Exploitation of the poor by the wealthy: China, India, Taiwan anyone?
If you look at the world today in 100+ years you could see elysium, if the rich continue creating the disparity.
