Lord of the Hidden Layer
A non-race way to get a "wrong side of the tracks" part of town would be to look at the pre-Potato Famine Irish in America: a LOT of young men, very few families or 'wise elder' types. Most individuals feel like they are alone against the world; the exceptions have a family / church / guild that can help them out in a pinch ... a little, because their resources are limited too. They all came here from somewhere else - a different 'somewhere else' for each individual. Without relatives or contacts in the city, you start on the ground floor and figure out 'The Rules', both written and unwritten, to get ahead in life.
