Let's be a bit honest here. California public infrastructure has hardly contributed to the windfall people are getting due to their work in the tech industry.
Does the UC system not count as "public infrastructure"?? I wouldn't be surprised if the UCs are the core driver for a lot of California's growth over the decades.
The UC system is a vortex for DARPA and NSF dollars.
Are saying tech workers don’t use public roads or mass transit to leave their homes?
Piblic roads are almost always maintained by the local municipality though and they collect the least taxes of any level of governmwnt yet deliver the most services. I've never bought that argument unless applied to the modern interstate system which was once a Federal responsibility but is now mostly state funded.
Than don't work there. Or try to influence how those riches are spend.
