This is the problem with for lack of a better term, millennial analysis of historical decisions on current markets.
Prop 13 was put into place because the state and municipalities were raising taxes left and right without consideration of things like fixed income individuals being able to stay in their homes.
There was good and bad in the measure. Good - to a point - raising the need to add taxes above 50%+1 vote, the bad, it applied property tax issues to both commercial and residential properties equally.
It's much easier to set up a business entity to span generations and avoid taxes than it is a private home.
The measure also masked an issue of use. A single individual who bought a house for $500k would pay more in taxes than a family who bought a house in the same neighborhood for $350k, yet if the family has children in the schools, they are paying less in taxes and getting more out. Most property taxes have multiple assessments for schools.
It does need to be fixed, but the conversation so far has fixated on residential and ignored the commercial impacts of prop 13.
