In my view FAANG jobs are beside the point. I've puzzled about this a lot, because I'm technically a "hardware person" with a degree in physics yet I'm also a good programmer. Many of my physics classmates became programmers. I could hypothetically bring myself up to speed on the latest software development practices and make myself employable at it. Maybe not at FAANG, but probably somewhere decent. But I've never made that jump.

I work in an office that has a sizable software development department, so I'm quite familiar with what they do, and what their work environment is like. It's not some distant mysterious place. They're my lunch buddies.

There are also lots of people who are quite bright, and do difficult mental work at lower pay, yet don't learn to program for whatever reason. Those of us who program know that it's actually quite easy, yet is an impenetrable barrier for most people, and we just don't know why.

There will always be somebody who makes more than you do, but it doesn't explain why people aren't all leaving their jobs for higher paying ones. Part of it may be psychological inertia -- I might be guilty of that myself. But I think another part is that we don't actually know the recipe for success.
