There’s been some neighborhood goings-on about the public housing building.
The building is surrounded by a fence because it makes it easy for police to catch criminals. No one is allowed to admit it, but most of the crime in the neighborhood is run out of the public housing building. Before the fence, it was easy for criminals to commit a crime and sneak back into the public housing. After the fence was put up, cops just waited for crimes to be reported and then immediately went to the entrances in the fence. Criminals would show up and get arrested. Crime fell dramatically.
Of course, in my ideal world, the people that live in the housing building would have to work. Any sort of work would do. Instead, modern policies require them to be idle if they want to stay on public assistance – efficiency does go up though, since the housing building is filled with the world’s least efficient people. As a result, the public housing becomes a magnet for drugs, prostitution, and random violence. This process is known as "progress."
