I'm pretty much convinced that the inflection point is "Director" at a FAANG or "VP" at a smaller company. Once you get to that point, it's pretty much impossible to fail downward. Worker bees rise up in level when they succeed (or the economy is good) and fall down in level when they fail (or the economy is bad). But, I've never heard of a Director or VP or anyone from the "executive class" getting a downgrade when moving jobs, regardless of performance and regardless of the economic environment. Once you pass that singularity, it's up, up, and away.
