Every single major population center that has distorted (high) housing costs relative to income, also has very strong protections for the existing home owners (NIMBY). "There are no coincidences..." The solution is terrifyingly simple: don't allow existing residents to block new housing developments. If they don't like it, they can move. This will probably never happen in the U.S., because the government no longer fu…
You seem to be coming from the perspective that people who don't live in a place should have more say over the nature of that place than those who do live there. To put it in your terms, why does it make more sense to tell existing residents "your place has to change and you can move if you don't like it" vs channel the new residents to other places where more housing is available and is available cheaper.
So all the outlying neighrborhoods/cities/areas -- MANY of which were built out in 40s to support the war effort as we were building liberty ships in the bay at an alarming rate - and all those women workers needed housing (rosie the riveter)...
So all these tiny packed neighborhoods needed for the 1940s workforce resulted.
Now we have a 2040 workforce need in the exact same way for building Liberty LLMS! (Expect of poisoning the dirt with war chemicals - we will find another similar metaphor digitally)
(most of saily city, alameda, treasure island, hunters point, candle stick, dog patch, etc - were all heavy industry for these ships and the naval base - and they were massive amounts of toxics buried in the dirt.
This is why hunters point was always ghetto - because they knew it was a Super Site - and so many people have gotten sick from it. Which is also why it was a very slow process to build stuff out new because new laws require environmental impacts which include soil sampling which reveals Super Site chemicals...
The very tip of Alameda Naval base was also a dumping pit now Super Site -- they decided that its cheaper to pound giant metal posts as a barrier to prevent the chemicals leeching into the bay - rather than spend 10 times as much to clean up the site properly.
and this just happened in the last 20ish years.. its been leaking into the bay since WWII
