Prop 13 needs to be extended to all persons perpetually under a certain income or over a certain age for their primary residence.
The other issue is new housing construction supply, which while providing new living spaces, reduces demand also impacts open space.
Maybe folks don’t remember the valley when there were fewer buildings. Heck, I remember a corn and pumpkin field across from the middle school I went to in south San Jose that’s now yet another soul-less strip-mall.
The Valley needs to balance concerns of open space/urban sprawl, building height/ ascetics, traffic/transport, property values, non-tech workers unable to save for retirement and homelessness.
Result: expensive housing and bad traffic. Prop 13 is a classic case of "road to hell paved with good intentions".
