And you get something for the income and sales taxes … some (not great, but some) level of public transit. Decently maintained roads. Few tolls in Southern California compared to other states, and they actually kept their word on eliminating tolls on the Coronado Bridge.
Free, well-kept beaches (yep, gotta pay in other states). Strictly enforced environmental regulations (that’s a good thing — ever been to LA in the 80s?) A decent public university system by national standards. Well-maintained public spaces, parks, museums, etc. A social safety net that’s somewhat better than other states if you lose your job or happen on bad luck.
I strongly doubt that Prop 13 will be overturned statewide. It would require a popular vote or state Supreme Court action to repeal. Plus there are already mechanisms in effect for localities to bypass it if their voters so decide (Mello-Roos and parcel taxes), so it needn’t be overturned.
