You ever notice how in a lot of cities, it's always the east side that's usually full of slums and ghettos and such, while the west side is a lot more afluent and opulent (and let me tell you, my city is no exception to this)? Apparently, there's actually a reason for this . . . and it dates all the way back to the Industrial Revolution. Y'see, the way the earth rotates and revolves affection the directional flow of our winds from west to east, during that period, winds would often blow all of that smoke, dust, soot, and other pollution into the eastern parts of cities, and people who could afford to relocate would do so into the western sides of their cities, while the poorer folks would remain behind in the eastern sides.
