Which public housing towers are you referring to?
I haven’t been there in a long time, but nobody in their right mind has been building “public housing towers” in the last 50 years. Mostly, they’ve been tearing them down.
Of course, I left 33 years ago because there were too many liberal idiots running the joint (and they still are,) so I might be wrong, but I don’t think this can be blamed on concrete edifaces.
I believe he’s referring to Riverside Plaza. There’s a picture here:
