> Silicon Valley's failure is in being unable to diversify effectively from a failure in city-building. What if it's the other way around? Public school didn't teach me about the Second Great Migration of black Americans westward during and after World War 2, and I was unaware that there was basically zero black population here until then. Check out the first graph in particular in this article: https://belonging.berkeley.edu/racial-segregation-san-francisco-bay-area-part-2 https://belonging.berkeley.edu/racial-segregation-san-franci... It's impossible for me to ignore the time correlation between these demographic changes, the civil rights movement, and the birth of California's various anti-housing policies like Prop 13. All the houses in my area of San Francisco had racial deed covenants making it illegal to sell them to non-whites, and this was new construction in the 1940s and '50s! That obviously became illegal in the 1960s so segregation became economic, locking in existing segregation by pricing out newcomers and letting existing residents pass homes to their kids down with no tax reassessment: https://fred.stlouisfed.org/series/OEHRENWBSHNO https://fred.stlouisfed.org/series/OEHRENWBSHNO
