Value added doesn't have much to do with it but there are other supply and demand factors at work. Truly remote friendly employers are still the exception so there is still high demand for engineers who are willing to relocate to the Bay Area. Someone not already there who is evaluating job opportunities will be considering a number of factors besides salary: cost of living, disruption of relocating to them and their family, lifestyle, culture, etc. and how they weight these factors will depend on the individual. They will be willing to accept pay lower by whatever it is worth to them to stay where they are.
