Remember that Amazon is a 25 year-old company. Bezos quit his job, took funding from family, and has always run a low-margin business, always playing a long game.
If I quit my job a bunch of people will be very negatively impacted. I can switch jobs and I can work on stuff in my spare time, but I can't go to zero income. Unlike Bezos, my family doesn't have anything they can loan me.
I'm stuck at my current job. I would have quit a few years ago (I've been miserable for 4 years) if I wasn't married. I'd probably move to my parents', do LeetCode and Hacker rank for a couple months, then land a high paying job to save as much as possible, and then retire early to a small farm in a low cost of living area.
