Living with poverty brings a whole bunch of new problems. I live in a community like this. Its noisy, filled with people with their own issues. I have alcoholics getting drunk in the parking lots making noise along with regular drunk driving. The police make regular visits to my complex. Noise, traffic, safety these are realities of dense living that effect quality of life. More people mean more chances to have babies next door, crying through your shared walls, more anti social behavior from people.
