The other viewpoint is that you provide the same value to your company whether you work in SF or in Kansas City (assuming WFH in both places). So basically you are saying "Hey, if I move to a cheaper place, please take 40% of my compensation and give it out to the C-Suite and shareholders, since I have no other options in my new city". I guess that is the reality of capitalism, and why ownership/equity is so important.
this is already messed up though.
Salary _does not equal the value you provide the company_. It represents the cost to extract the value. A quality senior engineer provides 3-7x the value of a junior, but only gets paid 30-40% more.
