No. In most bad neighborhoods people just stopped caring. Gangs don’t houses go derelict, people do. Gangs don’t turn up the TV when something is happening outside, people do. Gangs don’t ignore Kitty Genovese while she’s being raped and murdered, people do. You have to EARN living in a good neighborhood. It has to be maintained just like your house, your mind, and your body.
You are confusing cause and effect.
The people who care moved out of the bad neighborhoods long ago...no point in buying a house or staying in one in a high crime area if you can figure out any way to bail.
There are some sweet old ladies that do live in the bad neighborhoods because they are poor and cannot figure out an alternative—if they get out of line they will be dead old ladies as their houses get burned with them in it. They do care—about staying alive.
