Let’s say that you feel the place where you live is overcrowded.
How do you get rid of people?
Can’t kill them.
Don’t have enough money to pay all of them to move.
Here’s how you do it.
You live behind walls and turn the area around you into a shirthole.
Then, when enough people have left, you move the people who make it a shirthole.
Want to get rid of them?
Pipe in symphony music as loud as is permissable.
They’ll leave.
