But rent control in the absence of housing supply increases will undoubtedly exacerbate the problem, and at a steady 7% inflation would also slowly price out existing tenants.
Many parts of California already had rent control that was based on building age. Theoretically this could have been the best of both worlds--improved housing security for the majority of existing tenants, but an incentive for new construction, which would be excluded from rent control. Of course, the price of housing security would be marginally higher rent prices up front, but in the real world that's a reasonable tradeoff. Security and predictability are at the top of most people's hierarchy of needs, whether they admit that or not, and regardless of whether they'd willing pay for it. (Healthcare being a great of example of people predictably making irrational decisions, requiring government intervention to mitigate the consequences.)
Unfortunately, new construction in California is extremely costly for entirely unrelated reasons. I think most developers in California would have bargained statewide rent control for development as-of-right. That California permitted rent control again without doing anything substantive about lowering the costs of development is inexcusable. I'm sure lawmakers told themselves that they were buying the acquiescence of NIMBYs and local control advocates regarding future development as-of-right legislation, but they're just lying to themselves.
