Yes? as I understand it the general correlation between income inequality and crime is fairly well known, and the debate is on why it occurs and what can be done despite it. That said crime rates themselves are often more to do with reporting than with prevalence... IE if crime happens regularly people don't bother reporting it.

Okay, here's international correlations between income inequality and property crime .https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.86...

The best thing I could find for the time ranges you discussed suggests you are wrong about San Francisco, at least in terms of the last ~50 years and violent crime rates, which dropped 43% from 1975 to 2015. https://www.themarshallproject.org/2016/08/18/crime-in-conte...

The nationwide crime rate also went down during the same period, so I'm not sure that is really fair to your argument.

That said, more broadly here's evidence of a correlation between crime rate and income inequality, including property crime, using US cities that isn't time based. https://www.zippia.com/advice/crime-income-inequality/

Here's one showing that income inequality by neighborhood correlates to property crime rate. https://journals.sagepub.com/doi/abs/10.1177/004209801664391...

Here's a study about people on probation in San Francisco that shows that housing insecurity drive recidivism, and that that's particularly strong correlation for low level offenses like property crimes https://www.researchgate.net/profile/Leah-Jacobs-3/publicati...

Anyway, This paper suggests that increasing wages among low income workers decreases crime https://www.econstor.eu/bitstream/10419/90836/1/wp0017.pdf
