Have you noticed how little the media focuses on the actual platforms of most politicians and focuses on the spectacle and drama of politics instead? That distraction serve a purpose (for the owners of said media).
Also, a platform of higher rents and lower wages will usually be called "lower taxes" and "freedom from onerous regulations". If you want to see more of this type of propaganda, look at https://www.aei.org/ for instance.
This type of thing falls apart when analyzed too closely, which is partly why the media will use it to drive soundbites but won't dive in too deep.
Politicians get elected on a platform of higher rents and lower wages because the donations they rely upon come from people who want it and the media coverage they rely upon come from people who want it.
Lowering taxes doesn't lower wages.
Higher rents are caused by regulations, not freedom from regulations. You have to ask permission for something as simple as building places to live.
Prop 13 wasn't run on a platform of raising rents, was it?
And, Boston, NY, etc. rents are NOT as high as San Fran.
But while Prop 13 also affects politics around new construction, it's a far reach to use its long term effects on voter behavior to associate general concepts of lower taxes and less regulation with higher rents or lower wages.
Notably, it's a law that taxes people unequally.
i would be mildly surprised if "liberal" CNBC had even one person from common dreams on.
i'm not gonna dig through the new york times for examples where they cited somebody from AEI coz it's paywalled but it wouldn't surprise me if they, like CNBC do, routinely.
