I think it's definitely worth distinguishing between different classes of workers in Silicon Valley. It's hard to talk about tech ideology in a fully encompassing way because there are for sure dissenting voices. I think to some degree you can say it is the intersection of tech and wealth ideologies but there's definitely people that aren't wealthy that also espouse similar thinking so... tricky!

I adopt the handy framing of Silicon valley as a mindset rather than a place to help with this. There's a great photography book called Seeing Silicon Valley by Mary Beth Meehan that is all photos and stories of the precarious workers that don't necessarily work in tech. I keep it out in my office to remind me that silicon Valley is not just the rich assholes.
