I have noticed on HN a weird idea that most programmers are insanely rich and can pick and choose any job they like (I even saw one person say "lets be honest, none of us need a job..."), so I guess they're going by the logic that if you work for them you either endorse their worldview or don't care, which as you say I doubt is true for the majority of us
You can look up the average salaries for Amazon folks on sites like glassdoor. They're known for being competitive but not particularly larger or better than any other tech company. They pay well enough to live in a high cost of living area like Seattle but that's about it. Someone who spends a couple years at amazon is not going to be 'insanely rich'.
Well, not insanely rich. But let’s not pretend that the profession doesn’t compensate way above average and lots of options to choose from. definitely favorable for labor in this market, which is unlike most other labor markets.
