Senior-level engineers at a FAANGs are already a pretty rare and prestigious class of people. I'm a reasonably intelligent person and I've failed to pass the hiring bar at every FAANG.

And of course they don't "feel" rich. Lifestyle inflation is a thing. Trade the Civic for a Tesla; send the kids to private school; buy organic groceries; take international vacations every year or so; yet still find the means to save more money each year than the average household in the USA earns. Feeling is a state of mind, not a state of being.
