Established and older residents, especially those without children, see no reason we should be "Manhattanized" so more people can live here. They "like SF just the way it is, thank you". If you don't have kids, and you have rent control, you never really need to upgrade your 1BR apartment once you got it. Secondly, there is no upzoning, and subsequently no increase in density, without eviction, thanks to the rental market. Evictions aren't popular. The Tenderloin is completely insulated from any of this. Historical preservation is bogus, but has a history. The reason that some people argue for largely have to do with the projects in the Western Addition, which bulldozed a bunch of victorians to make what most people consider an eyesore. Local politicians don't really care too much. The reason being is any action they take pissed off established residents, who voted them in. That's changing a bit, as more people feel the pressure of the rental market and evictions. Still, there's more of an attempt to protect people who are established then there is an attempt to accommodate those who actually need housing, especially those in the middle class.
