While I don't want to diminish how bad it may be for those actually living in this situation, it seems to me that the only big problems about this -- besides "poverty makes non-poor people feel guilty" are essentially safety and sanitation. In this setting, there is too much fire danger, too much danger of the spread of disease, and danger of violence from less stable individuals living in the area. Aside from that, it's basically like going camping -- except the density is too high to be safe. One could argue that basically we (society) are merely failing to provide them with proper water, sewer, police, etc. because they're not doing this on privately-owned land and not doing it in a manner conforming to building codes, etc. Instead we kick them off the land periodically, hoping that someone else will take care of the problem.
