Other than NYC and a few other East Coast cities, the US has generally opted since the 1990s to pay for the poor to live in private housing rather than clustering a bunch of them together in public apartments. Housing projects in Chicago, St. Louis and other cities had become such nightmarish places and attracted such bad publicity from various murders and rapes that most of them have been closed and demolished. If you're interested in more about how and why public housing failed in the US, I'd recommend watching the documentary The Pruitt-Igoe Myth.
This is true.
Interestingly, there is a lot of public housing in Philadelphia but it is
not of the gigantic apartment tower variety- rather it is tiny little modern-looking homes and garden apartment-style construction in the midst of what used to be blocks and blocks of rowhomes. A lot of the historically worst-off neighborhoods thus have some of the most suburban-style construction.
For example (almost certainly the most extreme example; most of their construction is more modest), this public housing project:

I was around there when I visited Philly two weekends ago, and there is new infill construction popping up here and there. This image is kind of cherry-picked to find a block where that *isn't* in evidence... yet.

Not that I'm particularly a
fan of the architecture in that first picture, but I definitely have the sense that Philly public housing has avoided many of the worst sins of Pruitt-Igoe and their ilk. I don't know whether they got a later start and learned from others' mistakes, or Edmund Bacon did an even
better job than most people realize.
