Why do you think people are living this way? Do you think it's personal failure or maybe desperation? Where else do they have to go? If you tear down the buildings but don't address the root problem, do you think they will just stop existing or will they be forced to find a new spot to live? Were these places always this way? What would you like me to call them?

Please continue making assumptions about my personal life and deriding me for my choice of words rather than contributing something useful. I try to meet people where they are at, which means speaking to what they know. In this case, you seem to know the symptom, but not the cause.
