Isn't this what terrible public housing is already? Could it be less terrible or would it always devolve into a housing caste system because middle-/upper-classes would never use it? Set-asides for "affordable housing" in new developments are an absolute joke because there are very few units, they often have separate "servant-like" entrances, and may not be treated equally compared to other residents.
Also, the root cause isn't housing prices, it's a lack of supply because of NIMBYs, a lack of fast/cheap transportation, developing for maximum traffic/commute times like LA, and a lack of development around walkable/self-contained living areas.
