Prop 13 is getting repealed practically speaking through time, as the main beneficiaries of the low taxes die; and the taxes they dynastically transfer to their kids get capped; and as those kids choose to sell those homes and move to New York.
There is no one simple solution to e.g. poor performance of US public schools. Repealing Prop 13 isn’t going to close the achievement gap, it’s not even going to slow the fall of performance since 1993, let alone the pandemic.
So not only is Prop 13 sort of being phased out naturally, the repeal would simply put a bunch of renters against rising costs from landlords in the places that actually matter like LA and SF, and you know, as much as I hate Prop 13 in principle, everything has settled on a delicate homeostasis where the people who want to get it repealed fully - which will never happen - will get way more than they bargained for.
