(This is an expanded version of a Facebook comment, because Jeremy asked.)

Recently I came across an article about opposition to housing development in San Francisco. The headline positions of everyone involved are uninteresting: housing advocates want more affordable housing, housing developers want less. The really interesting bit is more subtle: at one point the developer says they’re still trying to figure out what the community wants and is immediately booed. What he means is that they are trying to figure out how the community would prefer to allocate a fixed amount of housing affordability across different levels of affordability: 50% of market, 80% of market, etc.
