Those things were created as alternative to substandard housing. My problem is, we dont see them as wellfare housing but the "new normal". Industry relies too hard on ppl living in those and paying too low wages.
Also, i dont care about visuals here but growing up in one of those, there's too little free space for human worthy life. Playgrounds covered in trash, srynges, dogpoop. Anything with grass covered in dogpoop. Sketchy people trying to snatch children being a daily occurance.
Its just too many people in one place. Not a left/right problem though.
