Tokyo is such a unique special case that I don't think it should be an example for anywhere else. I did not know about Vienna, spent some time reading about it! Seems that it had very expensive rents and government programs to build a lot of public housing cut those rents making it fairly affordable. So it is a good case study of this approach working. Although it seems most of that housing was built a century ago. I have to wonder how practical it would be to replicate that today. > Most cities aren’t very good at adding enough supply. Maybe it's just not that easy? Also, culturally in the US it's just never going to happen that a city owns half or more of all housing as a public service, so I suspect wishing for that is not realistic. So in the US, building housing doesn't happen unless it is profitable for builders.
