At one point, I'm fairly sure all those old people you're talking about were young people who felt like they deserved to live in their house. The difference is that, well, they were able to. I don't think you're intentionally saying "You came of age after 1980, kiddo, so suck it," but that's nonetheless the outcome. Proposition 13 certainly isn't the only reason that housing prices in California have skyrocketed, and housing prices have always been more expensive here than the US median -- but the gap between the California median and the US median started increasing immediately after Proposition 13 was passed and just kept accelerating.

The "won't somebody think of granny?" argument doesn't really work when advocating for a policy that disproportionately subsidizes non-grannies.

My house today is worth 2x what I paid for it a decade ago. Which is great except for the fact that housing costs around here are closer to 3-4x what they were a decade ago. Even if I wanted to sell, I couldn’t find any livable housing for the same price within the same area.

Buy. Borrow. Die.

Well, they do deserve those houses. If we expect young people to work, pay taxes and raise new generation. This is yet another middle finger to young people. No wonder birth rate is in toilet.
