An apples-to-apples comparison illustrates my point:
L10Y cumulative change in:
Bay Area rent: +46.0% [0]
Bay Area wages: +45.7% [1]
Vs:
Barcelona rent: +70% (if we believe TFA)
Spain wages: +30% [2]
Or:
Cumulative 2010-2020 change in:
Bay Area rent: +57% [0]
Bay Area wages: +34% [1]
which also looks bad (but not as bad as Barcelona L10Y). Indeed, there were lots of complaints about housing costs in SF then.

I guess it just doesn't look bad to me in terms of their real estate, thanks for pointing me to these better data sources.
