As an American East Coaster, where we have longer social experience with massive immigration (and with our own share of racism and segregation), lots of CA seems like a throwback to an even more highly segregated and almost racist time period. It's not quite the Deep South, but it's definitely uncomfortable with minority groups that tend not to be involved in tech or finance.

People lament the dying of ethnic enclaves like Chinatowns, but what it really means is that those ethnic groups are starting to integrate with the majority ethnic group.
