That's like 4-5 principal components back from the first principal component, which is that the places that need housing market vitality the most could not reasonably afford to acquire the housing to support it. The best school systems in Chicagoland are in the inner-ring suburbs, locked up for SFZ residents. Even if their municipal governments wanted to go all-out to fix that, they couldn't conceivably acquire the land and arrange the development.
Worth adding that "public housing" isn't the only or even the most common form of subsidized housing. There's no Faircloth limit at all to public-private subsidized housing with AMI-calibrated eligibility and rent, and that's a much more common form of subsidized housing than a "housing project". But it can't get built in meaningful numbers either, because it's simply too expensive.
