Earlier quoted context omitted.
What "housing deductions and childcare costs" does Google provide? A web search didn't turn up much and this doesn't sound like a standard benefit.
I also am having difficulty finding documentation for this, but I know it’s true. Many condo and apartment complexes around Google campuses have “preferred employer rates” that slash the rent for Googlers.
If such rates exist, they are uncommon or not often talked about.
There may be better proof out there, in which case you ought to provide it. But until I see something better, I am very skeptical.
