I mean ... you get to choose how you play the game.
If your goal is money and you are a manager then in any organization (not just Google) it's likely that income is going to be O(number of reports). More reports == more responsibility == more money.
But if your goal is to get something done and enjoy your job; you can play that game instead.
Perhaps one of the most life improving insights I've discovered about myself over the years is that I like managing engineers more than managing managers of engineers. The conversations in my week are just more interesting.
Now if I want to get a thing done that really takes 70 people then I either have to deal with it, or let someone else do it -- but just because "more comp requires more people" does not mean you have to aspire to more people. It's OK to like your work and want to get meaningful things done without aspiring to play the "more people, more money" game.
