I'm not sure how that contradicts what I wrote. It's above US median income, albeit without benefits. So, it's of course reasonable for someone to decide they don't need to work any longer with that income stream while others may feel differently.
At least for what I'm saying, it's not that someone would "decide they don't need to work any longer". This is what contradicts what you're saying.
It is about significantly improving your economic baseline, your p90 negative outcome. You can be making a million dollars a year and still be needy as hell. You need to keep your job, need to your investments stay up, need interest rates to stay down. If you're leveraged, there's a decent chance you'll go broke on a long enough timeline. And you'll always be partly aware of it. Your baseline is getting a job you hate so you don't go homeless.
If you have 2 million in the bank and don't leverage too hard, your baseline is being the average American while working 0 hours a week. You can do that until you figure out whatever is next, instead of sending out resumes.
