District 9

I was talking systems with a coworker today, he had just finished watching District 9 and we were talking about it. He said that it was unrealistic to have that many aliens live on a planet for so long and not have an uprising. I then countered this with the 'drift to low performance', my new favorite type of system failure. If aliens came to earth and lost their one resource needed to have their weapons and modes of transportation then after a while more and more would feel hopeless and just start to give up, until they reach the point where practically no one cares anymore and they just go on with living with the available resources. But of course since it is a movie there has to be a few left who are able to be the heroes. :)
