A) ghettoization in the form you describe is a zoning problem. Mixed-rate zoning is a thing, even in major cities in the US, and there's no reason social housing needs to be geographically isolated from market rate housing. As you point out, that's really unhealthy. I submit that the US has just implemented public housing extremely poorly, especially on the federal level, and Section 8 vouchers are going to be a much larger bill to pay to the American taxpayer than simply building public housing to begin with. B) From a healthcare perspective, both housing and rehabilitation are necessary for the person to be able to function stably. I would argue that this type of housing as well as drug decriminalization is necessary to treat the underlying poverty (and resulting crime). EDIT: wording.
