it only turns into "ghettos" cause they end up under or defunded, leading to disrepair and poor quality housing. so the only people that end up living there are the ones despirate enough to live in poor conditions.

keep the funding up and more diverse people will live there

also "mixed income" is a misnomer cause you are only gonna get a mix of the economic bottom half or so. You won't get anyone rich living public housing and we should stop pretending like that will happen. The rich always find a way to segregate themselves away from poorer people.
