@aral @davidsabine also even * if* we demand #profitability there are like dozens of #RealEstate #cooperatives that were spun off for #PublicHousing holdings (instead of selling off said #housing units to big corporations for less than a years' rent each) in #Germany that do maintain and build #AffordableHousing and provide basically #TennantOwned (#deposit = shares in the cooperative) housing...
At least two of them are the reason rent in my hometown didn't skyrocket!
