I don't know what to say, except that if you're relying on Glassdoor as an indication of L5 compensation at Google, you're making decisions based on bad information. And, yes, equity can be 50% or more of TC at those levels, which have salaries well above 110k.
If there's someone reading this who's interested in working at Google or Facebook but worry the compensation might be too low to live a good lifestyle in the Bay Area, ask actual people who work there for input instead of people who gawk in disbelief at these salaries.
