"Absolute belief" is something you inferred that wasn't there.

Human nature is what it is. Bring enough of any group of people to another place, there will be cultural replacement.

What about the self reflection of those who let themselves be underpaid and displace the local culture for a quick buck? It seems like you're being sanctimonious.

The Bay Area can keep Man Jose, Sunnyvale, and the East bay. I avoid American yuppies without life experience and the precariat too, so don't feel too special.
