I obviously think it's mostly absurd if you think a woman who bought 50 years ago in SF has a house worth only 50K. The vast majority of houses in SF that would have cost 50K, 50 years ago. The average home in 1976 was $65K,[^2] and the median home price last year in SF was $1.4M, at effectively the 90th percentile of American net worth. If you don't think top 10% of wealth in America counts as wealthy, then I don't know what to tell you.

So it’s a win-win in a way - either you’re rich enough to pay the mortgage on an expensive property in which case lowering property values in expensive locations is a bit redistributive or it won’t affect you really in which case who cares?
But does it make this old lady wealthy, if she is not selling her house and moving to Arkansas, where $1M would go much farther than in SF? May it be that she's struggling with her day-to-day expenses in SF?
