The salient point is that a $600k/year salary is uncommon or even rare even at FAANG. There are a lot of engineers who could work at a FAANG or FAANG-like company, but most of them will never see $600k/year in compensation.
Also, sure, there's a distribution of ranges at a given level across FAANG (and all tech companies, really--though I think it's bimodal in that there is "FAANG" (and FAANG-like or near-FAANG) and "everything else"). Also, Netflix has a rather unique (for the tech world) approach to employment, in that they will absolutely let someone go if their performance is even slightly off or there is a pivot in strategy (rather than, say, relocate an engineer to another team). Employment there is a riskier proposition than at other FAANG companies. They have to bake that premium into the price they pay for labor.
