Indeed so. One hardly needs to be a "racist" to think they're a bad solution. By the way, they're just as bad a solution in the UK -- where most of the underclass is white, not black -- as they are in the USA. (So much for the "inferiors'" darker skin color being the issue.)
It is not surprising. These sort of buildings, as the philosopher Andrew Oldenquist said, enter into a conversation with the tenants. It tells them: "You are not like other people. You are welfare. We assume you will be violent thugs, so we designed the buildings to withstand a lot of vandalism and arson. We assume you are all alike, so we designed the buildings without a shred of individuality or neighborhood feeling. We assume you will all kill each other, given the chance, so we designed the buildings where each apartment is isolated from the other. You are worthless, and this is the special kind of building where we put people like you."
Is it any surprise that this is the result? I do not wish to give architecture some sort of magical power, nor does Oldenquist (he is deliberately emphasizing to make a point), but there's certainly a lot of truth in his criticism.
