Maybe many would not destroy or abandon more like neglect or facilitate illicit activities. There is a lot of social work to be done but no one wants to pay for it.

There were (I think still are in many places) projects where municipality in Europe would create social housing and putting let's say "not that lucky people" in one place does not help but creates its own problems. Where just providing flats was not enough because later no one had time do social work or money to pay social workers.

I can say as a kid I was living in such a project, all of the "normal-city" people would refer to us as "special place" or "street of magic". Many people made their lives better or at least make it stable there. Some managed to burn down their flats creating problems for their neighbors. Then there was loads of shady stuff going on.
