Mostly no, they do not. PIs are typically paid little, given their worth on the market for their skills. Even though he was 'famous', he got his Nobel at ~70 years old, meaning that he spent most of his earning years 'unrecognized'. I know you can look up any University of California professor's earnings here: https://www.sacbee.com/site-services/databases/state-pay/art...

For instance Professor Vickram Chandra of UC Berkeley [0] made ~$91k in 2016 [1]. Other professors make more, like Professor Alexandrova of UCLA who make ~$146k in 2016 [2]. You can poke around the UCs and compare. Do remember that most PIs labor in grad school for ~7 years, earning barely anything.

I do not know of other databases for other universities that do this, but many US states have sunshine laws that make professor's salaries public information. I know that Colorado also mandates that all public employee's emails are public information too and I think other states do this as well, though I do not have a list of them.
