I can't say what Google's policy is, even after looking.

However, a least in some countries where they pay for parental leave, it's capped.

For example, it appears that in Germany a VP making EUR 500K/year isn't eligible to receive any Elterngeld.

And in Denmark it maxes out at DKK 4,465/week = USD 669/week = ~$35K/year -- both the VP and entry-level employee in your example will get the same benefits.
