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.
Not that I mean to pry but that sounds like it benefits everyone involved if it meant the pay raise – get a few months in savings in then bootstrap from there. Easier said than done I know.
