Similar experience with a friend of mine. I feel like these high salaries only apply to people who habe worked at one of these companies for a looong time.
High salaries are relative. $90k is a high salary for most people in the world, even for tech workers outside of Silicon Valley.
High salaries are when a grey beard consultant is bought in for a few months to fix something or implement some new regulation. And I don't think it was that high was ever as high as financialised tech companies managed.
