I know the price of specific apartments. 2br went up from 1600 to 3200-3800(depending on month price varies), and many blue color workers who used to live there moved from that complex.

> SF median rent

your graph shows not SF (which is actually not silicon valley) but SF-Oakland metropolitan area. SF rent likely raised more than that.

> SF minimum wage went up 93%

Min wage is an outlier, they couldn't afford rent then and now.

Another factor is taxes, while wages increased, wages after taxes increased slower, because pushed income to another bracket.
