The false assumption is that you need to have 100 people under you to be a Director. It's a title, not an organizational role.

Managers benefit from a seniority system at places like Google because you get automatic level bumps after so long. Sure, the ladder will get longer at the top (there will be VPs and SVPs and EVPs and SEVPs and CVPs) as they have to invent new levels up there, but the fact is that it's just much easier for you if you're a Google manager with guaranteed promotions for average performance, as opposed to an engineer who has to do something special to get Principal+.

You could be right, though. Google may have to do an honest layoff (as opposed to the dishonest stack-ranking/PIP bullshit which is a layoff masked as a "low-performer initiative") and, when that happens, a lot of managers are going to find themselves on severance packages. The ones who manage to hold on will still be getting the guaranteed title bump every 2-3 years, unlike engineers to whom no guarantee is made, but it won't be the same, and being a manager at Google won't be the cushy, write-your-own-performance-reviews job that it historically has been. The churn will free up positions, but the game will (as you noted) feel more zero-sum than it is when it's expansion that creates them.
