AFAIK, the number considered is salary, so the number is decently high, even for bay area. There are some exceptions like Netflix, but a lot of companies pay majority in equity, especially at higher salary levels.
I don't know how easy/difficult would it be for companies to move from equity based compensation to normal salary though, if something like that is implemented.
