Defied: Alice and Bob immediately start working to make the world better.
Discussed: "Why does this place have to suck?"
Conversed: "Hey, 'realism' does not necessarily mean 'ugly hellhole full of crime.'"
Because life in the world is so terrible, many people fail to see the point in living and are Driven to Suicide as a result. Those that aren't Driven to Suicide simply end up loathing the world more, and are further entrenched in their hopelessness.
The government running such a Hellhole find keeping everybody oppressed and miserable much harder than they thought, with constant rebellions, strikes, and people just wanting happiness or just a square meal on the table.
The horrible conditions of the world makes the tiniest glimmers of the most ephemeral happiness treasured beyond anything. The people of the world are driven to become hedonistic, unfetteredUbermensches, caring little for what happens to other people or a world beyond saving, just so long as they can be happy for just one moment.
Running a dystopian government would be hard if the place wasn't full of Apathetic Citizens who are only looking out for themselves.
The world is such a terrible place because of people like that, thus creating an endless cycle. Some people realize this and become Knights in Sour Armour. However they end up failing to the world a better place.
