Over populations, pollution and rubbish everywhere.
Welcome to Elysium!
Elysium did not make sense to me though I did not finish the movie. I thought if there was this place up there that was so good and life on Earth was so bad, surely someone down on Earth would do something about it. Criminals on Earth had the technology to send a space shuttle to the space station with people on board so why not send a missile that separates to dozens of warheads as it closes in on the space station and blow the space station up? If it came to a war between the people on Earth and those on the space station, if the Earth people got in a first strike like sending a shuttle up with an atomic bomb in it then that would be the end of the war.
I also thought it didn't really make much sense to have the wonderful health machines just on the space station. If one of the people up there decided to take it down to Earth and set up a business healing people they would become the richest person on both the Earth and the space station. If there was a prohibition on exporting the technology to Earth then someone would come up with a way around it as they always do because the incentive was incredible, crappy healthcare on Earth vs perfect health care on the space station.
Finally I thought the people on the space station didn't seem that bad, its not like they were eating babies sent up from Earth or using Earth people's heads for soccer balls. The people on the space station seemed like pretty normal sort of people enjoying their good life. Their good life didn't seem to be at the expense of the people on Earth. We didn't see space ships constantly being sent up to the space station to supply the people there with stuff they needed while the people on Earth starved. So why would the people on the space station put up with the injustice of the situation, especially when its clear there was a lot of money to be made by sharing the technology with the people on Earth.
So from what I saw its a bit of a morality tale to put something in the future what is happening now, how the rich westerners are closing their borders and their minds to the masses in other countries and not wanting to share their wealth. Unfortunately this message is a bit behind the times as the reality is western countries have slowed down their economic growth, most notably in Europe. Meanwhile many people in other countries are greatly improving their lives and their wealth especially through using improved technology.
