Its not always bad. In areas that are already urban that scheme can be combined with fewer parking places near public transit and result in a larger overall supply of housing. And mixing poor families into nicer neighborhoods rather than clumping them together into a Housing Project can mean they're not in a food desert and have better-funded local schools and a better-maintained building, maybe be closer to where they work. As well as increasing neighborhood diversity and interaction in general. It's not helpful to profoundly destitute folks who need lots of services but it can help people who just need a home they can afford.
