If SV and SF allowed for the construction of additional housing, there would not be a downstream housing crisis in Denver, Austin, etc. The policy decisions of a handful of city councils of the suburbs on the West coast has had a huge impact on these cities -- and has indirectly displaced residents, disrupted local economies, and pushed many people into homelessness.
Housing policy in major economic zones in the US is a national issue, and should be treated as such.
This doesn't even touch on the wider problem of income inequality itself.
If we're being completely honest, the average American would be much, much better off if SV had never produced a single unicorn.
