Proposition 13 was advertised to protect the poor and elderly citizens, but its design does not target them. In particular, it benefits those who don’t need help: commercial landlords, rental landlords, and (after Proposition 58/193) feudal estates. And it harms those poor and elderly who are unable to purchase a house. In short, it is an entitlement that benefits homeowners, at the expense of renters and home-seekers. It takes some tautological reasoning to defend its poor design if the goal is protecting lower income households; see the Stevens dissent to Nordlinger v Hahn https://www.law.cornell.edu/supct/html/90-1912.ZD.html
